HI-985394 Pool Line Checktemp Digital Thermometer
The Pool Line digital thermometer is a highly accurate thermometer with a 3m flexible, silicone cable connecting to an AISI 316 Stainless Steel Weighted Probe. Ideal for testing in pools, hot tubs and spas.
The probe incorporates a NTC thermistor sensor for temperature measurement. Thermistors make it possible to obtain extremely high accuracy in a very short period of time.
This probe is compliant with HACCP requirements and can also be used for fish farms and water reservoirs where the operator can simply stand on the edge of the water and dip the probe in.
The Hanna CAL Check feature has been incorporated into these thermometers for reliable and accurate measurements. CAL Check automatically runs a self-check diagnostic upon start-up and reports status back to the user.
