Series 400 Thermistors

Series 400 YSI’s Series 400 Thermistors are the perfect complement to Hart’s new 1521 and 1522 Handheld Thermometers. Like the 1521 and 1522, they’re inexpensive, accurate, and easy to use.

Four models are available to match a wide variety of applications. The 5671 General Purpose Probe, 5672 Immersion Probe, and 5673 Surface Probe are each accurate to ±0.2°C from 0°C to 75°C.

The 5674 High Accuracy Probe is accurate to ±0.05°C from 0°C to 70°C.

Each comes with an INFO-CON connector (unless otherwise specified) and can be used interchangeably with Hart’s Handheld Thermometers without any programming of the meter.

Each Series 400 Thermistor is tested by YSI for compliance with the interchangeability tolerance level for that particular probe, and a certificate of traceability is included (without data). Optionally, a two-point system calibration can be ordered from Hart for your thermistor and 1521/1522 combination
