Applications: Production Lines, Food, Metal, Glass, Ceramics, Rubber, Synthetic Resin, Medical, Petrochemical, Automotive, Electrical, Industrial


One of its most unique features is the E-TEACH function for automatic adjustment of the emissivity ratio. The On-Line Infrared Thermometers have two choices of analog output: TV-type (1mV/°C) which connects to such devices as a panel meter, or TA-type (4-20mA), for long distance transmissions. An optional air purge collar adapts this unit to dusty environments.

Applications range from the manufacturing of food, metal, glass, ceramics, rubber, synthetic resin, to medical, petrochemical, automotive, electrical and industrial uses.

The On-Line Infrared Thermometers, Models 15201-15204, are engineered specifically for use on the production line to measure moving objects quickly and accurately from a safe distance. These infrared thermometers measure targets within a temperature range of 32°F to 932°F (0°C to 500°C) with a 500 millisecond response, at a ±1% level of precision.

Misc Info
  • DeltaTrak’s Real Time Loggers have been a game changer for our trucking program. Having the ability to monitor temperature while trucks are in transit has given us peace of mind knowing the quality of our product has not been compromised. The alert notifications, light sensors, and GPS tracking are just some of the great features that have allowed us to make pro active decisions that have strengthened the integrity of our product. The FlashTrak Cloud Service is easy to use and is a great tool to compare and analyze data. The FlashTrak App is super convenient as well. We have used other reliable DeltaTrak products for many years and we were excited to see these added to their lineup!

  • When it comes to making sense of data (in the supply chain) we have found a partner in DeltaTrak. The fact that I could recharge the real-time logger and the dual batteries made a lot of sense to me. It was user friendly and easy to use. With the uncertainty and complexity of today's supply chain, having an effective chain of custody system is not only a clever idea, but a requirement for effective handling of perishable goods.

  • It is my pleasure to recommend DeltaTrak to your company. During these times of crisis, we were fortunate to work with DeltaTrak to source top of the line Non-Contact forehead thermometers and PPE supplies at a real market price.

    As a healthcare organization, we are a common target for price gouging and abusive practices from several vendors. With DeltaTrak, we found a partner that understands our needs and who always provide world class customer service.

  • Dear Fred, I would like express my appreciation for the good business relationship we have had during 2018. The excellent work of Mr. Jorge Hurtado has given me the confidence to continue maintaining our commercial relationship with the DeltaTrak brand.

    Mr. Jorge Hurtado's customer service efforts are outstanding, especially in finding solutions to the challenges that may arise in the commercial process. In my opinion Mr. Hurtado's professionalism is a model for any company, especially when the client is thousands of kilometers away from Modesto, CA. I look forward to strengthening our successful relationship into 2019.

  • Thank you Juan Solorzano for paying us a business call 4 years ago. The DeltaTrak brand is the majority of our Temp Recorder business. ALL our Walmart/Sam's orders carry the DeltaTrak Temp recorders for the past 4 years without a single problem with any Walmart DC. When you have a load of 18 different orders on a single truck and temp recorders on each order, WOW what a savings your DeltaTrak brand has save us. Yes, Walmart has accepted the DeltaTrak Model with no problems.

  • This upcoming fall will mark our 4th full season using DeltaTrak recorders. They are competitively priced and the customer service is always exceptional. We have never had a customer issue with one of their units and we don’t expect to. We use a wide range of DeltaTrak products and we have been more than happy with every one of them.
