Digital Pocket Test with Temperature Alarm

The Cooper-Atkins DFP450W Digital Pocket Test with adjustable Temperature Alarm was specifically designed for the harshest foodservice environments. The Instrument can be programmed to provide a visual alarm (blinking display) once the set temperature is reached. The initial default alarm temperature is 140oF (60oC). Potentially hazardous mercury thermometers are often used to check the extreme water temperature of commercial dish water. Eliminate the risk of a mercury spill; this digital thermometer with alarm stores the maximum heat registered and is waterproof. Guaranteed Accurate for Life means there is no need of field adjusting of calibration settings and no risk of introducing error into the instrument.

    Waterproof thermometer

    Great service and product. Very reliable and good quality. Got them 1 day later but is worth.

    One Of The Best

    This thermometer is the best instant thermometer that I've used, I say that because I had the same thermometer prior to purchasing this one four or five years ago. It's accurate, quick, and easy to use. The original battery lasted the entire time I had it. And it has a lifetime warranty which I had forgotten about but as good as this one was for me it was nothing to purchase another one. I was very happy with it and I thing you would be also.

    La Crosse Technologies V10-TH

    The La Crosse V10-TH Wireless Weather Station (Model No. C84343) is absolutely wonderful. The setup was easy with the Quick Setup Guide provided with the unit. The packaging contains additional support information with the website and phone number if there are questions. I especially liked the daily high low readings and the color on the unit! Tech Instrumentation provided great communication as to the availability of the product and shipping details. If fact, it arrived one day prior to the estimated delivery date. I would absolutely recommend this product and Tech Instrumentation for anyone looking for an indoor/outdoor weather station!


    I needed a replacement as my original sensor no longer worked. This one works fine.

    Excellent Customer Service!

    I can't way enough about the customer service at Tech Instrumentation. I was looking for a hard to find specialty part, which the manufacturer told me would need to be custom made. After calling and speaking with a representative at Tech Instrumentation, the part was located and order was filled, right over the phone. Delivery was prompt, and instrument is working great. Highly recommended company for lab supplies!

    Worked great

    Put batteries in and worked great
