Handheld Two-Channel Platinum Resistance Temperature Digital Display Meter
The TM-5012B is a compact, portable, and cost-effective handheld thermometer. Although it does not include an internal temperature control device, it minimizes the impact of ambient temperature variations through temperature compensation technology, meeting the measurement accuracy requirements for Standard Platinum Resistance Thermometers (SPRTs). The unit is also compatible with PT-100 industrial platinum resistance thermometers. It features built-in storage for calibration parameters of up to five thermometers, allowing users to directly select settings by thermometer serial number. Powered by a built-in rechargeable battery, the device is equipped with an OLED display and supports data download functionality.
