Product Overview

Here’s a brilliantly simple tool to take the guesswork out of your kitchen’s safety checks. The GJ059 Dishwasher Temperature Test Strip is a straightforward, reliable way to verify that your commercial dishwasher is reaching the correct sanitising temperature. It's a small strip that provides big peace of mind, giving you a clear, permanent record of a successful wash cycle.

Designed for any professional kitchen where hygiene is non-negotiable, these strips are essential for restaurants, pubs, care homes, schools, and  cafes.

They provide the physical evidence needed to support your HACCP procedures and  daily due diligence logs, ensuring you’re always ready for an inspection.

With a clear colour-change indicator and  a space for a date and  signature, these strips transform a routine check into a documented, verifiable part of your food safety management system.

Expert Review and  Insights

In my line of work, I see kitchens fail inspections over the simplest things. These little strips are a maintenance dream because they close a common compliance gap. They offer undeniable proof that a machine is doing its job correctly, moving your logbook from a list of guesses to a collection of facts. It's a low-cost, no-fuss tool that every single professional kitchen should be using.

  • Foolproof Evidence: The permanent colour change is an EHO's dream, offering clear proof of sanitisation.
  • Single-Use Only: They’re disposable by design, so you’ll need to factor in ongoing stock replenishment.

Case Study: Real Business, Real Results

The team at 'The Anchor Inn', a busy seaside pub in Whitby, wanted to tighten up their HACCP procedures after an EHO visit highlighted a lack of temperature records for their glasswasher. They needed a simple, reliable solution that any member of staff could use.

Since we started using these GJ059 temperature strips, our daily checks are quicker and  we have a physical logbook full of proof. It's taken all the anxiety out of our compliance paperwork and  the staff find them incredibly easy to use.

Robert Davies – General Manager

The result was immediate: The Anchor Inn passed their next EHO inspection with flying colours and  now has a streamlined, stress-free system for proving their commitment to hygiene.

Installation and  Maintenance Guide

Using The Strips Correctly

  • Ensure the item you place the strip on (e.g., a plate or tray) is clean before the test.
  • Position the strip on the item, facing the water jets. Place it in an area you feel might be a 'cold spot' for a true test.
  • Run a complete, standard wash and  rinse cycle in your commercial dishwasher.
  • Remove the item after the cycle finishes and  check the strip immediately for the colour change.
  • Fill in the date and  your initials in the spaces provided to validate the test.

Storing and  Managing Your Strips

  • Store unused strips in a cool, dry place away from direct sunlight or heat sources to maintain their accuracy.
  • Once used, attach the completed strip into your daily or weekly HACCP logbook as a physical record.
  • Keep the logbook organised and  ready for inspection by an Environmental Health Officer.
  • Keep an eye on your stock and  re-order when you get down to your last few strips to avoid running out.

Buying Guide: Choosing the Right Compliance Tools

Not sure what you really need to keep your kitchen compliant? Here’s a quick guide to making smart choices for your food safety plan.

Know Your Target Temperatures

UK food safety guidelines require a final rinse temperature that effectively sanitises. These strips are calibrated to confirm this, taking the ambiguity out of your checks.

A Paper Trail is Your Best Defence

An EHO wants to see consistent, long-term proof of your procedures. A physical logbook with dated and  signed dishwasher temperature test strips is difficult to dispute.

Consistency is Key

Testing shouldn't be random. Decide on a schedule—daily for very high-use sites, weekly for others—and stick to it. This demonstrates a proactive approach to safety.

Don't Trust the Machine's Display Alone

The temperature on your dishwasher's screen is the water in the boiler, not necessarily the temperature hitting the plates. These strips measure the surface temperature, which is what truly matters for sanitation.

Simplicity Equals Reliability

You don't need a complex digital system to prove compliance. A simple, reliable tool like a commercial dishwasher temperature strip is often more effective because staff will actually use it correctly every time.

Frequently Asked Questions

Q: What specific temperature do these strips verify?

A: They are designed to confirm that the surface has reached the industry-standard sanitising temperature, typically around 71°C (160°F), which is required for effective commercial warewashing.

Q: Are the dishwasher heat test labels reusable?

A: No, the colour change is permanent to provide a lasting, tamper-proof record for your logs. Each strip is designed for a single test cycle.

Q: How do I get the strip to stay in place if it's non-adhesive?

A: You don't need to stick it. Simply lay it flat on a plate, place it in a glass, or slot it into a cutlery rack. The force of the water is not enough to move it significantly.

Q: Will they work in my specific brand of dishwasher, like a Hobart or a Winterhalter?

A: Yes, absolutely. These strips are universal and  function based on temperature, not the machine's brand. They work in any commercial dishwasher.

Q: Why are the 'Date' and  'Signature' fields important?

A: They allow you to create a fully accountable record. By signing and  dating the strip, you verify when the test was done and  by whom, which is best practice for HACCP and  EHO inspections.

Q: Why is a non-adhesive strip better?

A: It ensures that no sticky residue or glue is left behind on your freshly cleaned and  sanitised crockery, glassware, or the inside of your machine.

Q: How many tests can I perform with one pack?

A: Each pack contains 25 individual thermal indicator strips, so you can conduct 25 separate tests.

Q: Is this better than using a temperature probe?

A: They serve different purposes, but for EHO evidence, these are often preferred. A probe gives you a temperature at one specific moment, whereas this strip proves the maximum temperature was reached on a surface during the entire cycle.

Add Review

The Unseen Guardian of Your Reputation

A simple dishwasher temperature test strip does more than just tick a box for a health inspector. It acts as the unseen guardian of your business’s most valuable asset: its reputation. In an age where a single bad review can cause lasting damage, demonstrating an unwavering commitment to customer safety is paramount. Using these strips is a proactive declaration that you take hygiene seriously, moving beyond simply hoping your machine works to proving it does. This small, consistent action builds a powerful culture of accountability within your team and  provides complete peace of mind. It’s a tiny investment that protects you from the significant financial and  reputational costs of a failed inspection or, worse, a hygiene-related incident. Ultimately, it’s not just about compliance; it’s about building trust with every single customer who walks through your door.

How an Irreversible Indicator Creates Bulletproof Records

Ever wondered what 'irreversible' really means for a thermal indicator strip? It’s the single most important feature, and  it’s actually quite clever. Unlike a regular thermometer whose reading goes up and  down with the temperature, the colour panel on these strips is designed to make a permanent, one-way change once a specific heat is achieved.

Think of it like a safety seal on a jar. Once it's broken, it can't be unbroken. Similarly, once the strip's surface hits that critical sanitising temperature (e.g., 71°C), the colour flips and  stays that way forever, even after it cools down. This creates a physical, undeniable piece of evidence that the correct temperature was met during the wash cycle. It’s this permanent record that an EHO values, as it can’t be faked or altered after the fact, making your compliance log truly trustworthy.

Who Should Buy This?

  • Restaurants & Pubs: To ensure every plate, glass, and  piece of cutlery meets strict food safety hygiene standards.
  • Schools & Canteens: For maintaining a clear, simple log of dishwasher performance for routine health and  safety checks.
  • Care Homes & Hospitals: A critical tool for infection control, proving sterilisation temperatures are consistently met for vulnerable residents.
  • Cafes & Delis: The most affordable and  straightforward way to validate your warewashing process without buying costly equipment.
