Tempco: Temperature Monitors

Portable 6-Station Temperature Monitor
These thermocouple monitors were designed to assist field technicians with testing or calibrating HVAC/refrigeration systems, baking/curing ovens, motors, engines, and much more. Instant response circuits allow a technician to compare up to 6 temperature probes quickly.
These circuits have been optimized to deliver accuracy and stability over a wide environmental range. The durable carrying case is compact and features a compartment for storing wire and probes.

Design Features

Thermocouple calibrations available are K, or J linearized in four sections for good accuracy.
RTD Cold Junction compensates accurately for ambient temperature changes as fast as 2°/min.
High Impedance Circuit allows use of probes with up to 1000 ft. of 24 ga. wire; several transformer- isolated monitors can connect to the same probe.
1/2" High LCD Display is sunlight readable.
Powered by 9V alkaline “transistor” battery.
Durable Rotary Selector for displaying 6 thermocouple inputs.
Large Pointer Selector Knob clearly indicates the monitored location.
Polymer-Coated Circuit will perform indefinitely even in high humidity environments.
Made in the United States and warranted against material or workmanship defects for 1 year.

12-Station Temperature Monitor
These thermocouple monitors were designed for industrial or commercial applications that require monitoring of up to 12 locations economically. The circuits have been optimized to deliver accuracy and stability over a wide environmental range. Typical applications include monitoring HVAC systems, baking/curing ovens, food or medical freezers, solar installations, refrigeration equipment, motor bearings, engines, etc.

Design Features

Thermocouple calibrations available are T, K, J, or E linearized in four sections for good accuracy.
RTD Cold Junction compensates accurately for ambient temperature changes as fast as 2°/min.
1/2" high Red LED Display provides excellent readability.
Large Pointer Selector Knob clearly indicates the monitored 1 of 12 locations.
Polymer-Coated Circuit will perform indefinitely even in high humidity environments.
Made in the United States and warranted against material or workmanship defects for 1 year.
