Handheld Water Resistant Thermometer

In applications where clinical accuracy is not mandatory and cost is an important factor, the PTM1 is Physitemp‘s most compact and economical thermocouple thermometer.

The Model PTM1 is a high performance, precision hand-held instrument for the measurement of temperature using Physitemp’s Type T (copper-constantan) thermocouples (will also accept J & K). This versatile instrument measures temperature in both °C and °F. The internal memory of the microcomputer stores the minimum and maximum measured temperature range for instant recall via the LCD display.

The PTM1 operates on four “AAA” batteries. The touch mode keys are highly reliable with tactile and audio feedback. The resetting of parameters is not required when power is restored.

The unit is also equipped with a non-volatile memory allowing the user to store 50 different sets of readings. This unit will assign a site number for each set of readings stored, so the user can review the data easily.
