Description

The TH-21 Series thermistor probes are constructed with the 55000 Series glass encapsulated thermistor elements which provide excellent stability and accuracy. With a maximum continuous temperature rating of -80 to 200°C (-112 to 392°F), and intermittent operation to 250°C (482°F), these thermistor sensors can be used in applications previously out of reach of epoxy coated thermistor sensors. The probes can be ordered in any length but we highly recommend a minimum immersion depth of 1.5". Short probes run the risk of error due to stem conduction effects.

† All prices on this site are shown in Singapore Dollars.
Note: For lengths other than 6", change “-0600” in model number to required length and add $1 per inch greater than 6", (example: 9" = 0900, 41/2" = 0450).
For 1/8" probe diameters, change “-1/4” in model number to “-1/8”, no additional cost.
For 3K, 5K or 10K Ohm thermistor elements change “-2252” to desired resistance.
•For Dual element probes, add "-DUAL" to the end of the Model Number and multiply the price by 1.75
