High-accuracy IP65 digital pool thermometer with 3m cable, CAL check feature and AISI 316 probe. Ideal for pools, spas & HACCP.
The Pool Line HI985394 Digital Pool Thermometer delivers high-accuracy temperature readings for a variety of aquatic applications. This reliable instrument features a flexible 3-metre silicone cable connected to a weighted AISI 316 stainless steel probe, housing a sensitive NTC thermistor sensor for rapid and precise measurements.
Incorporating the innovative Hanna CAL Check feature, the thermometer performs an automatic self-diagnostic test each time it is switched on, confirming the device's operational status to ensure consistent and dependable accuracy. Designed for convenience, it is supplied with three AAA batteries, offering a battery life of up to two years, especially when utilising the configurable Auto-Off function, which can be set to 8 minutes, 60 minutes, or disabled entirely.
The large, clear display provides excellent readability across a wide viewing angle and supports an extensive temperature measuring range from -20°C to +80°C. Its robust IP65 rating guarantees protection against dust ingress and low-pressure water jets from any direction, making it suitable for use in damp or splash-prone environments.
Beyond monitoring pool and spa water, this versatile thermometer is an excellent tool for fish farms, water reservoirs, and any scenario requiring accurate liquid temperature checks. Its 3m cable allows an operator to safely take readings from the water's edge, and the weighted probe ensures it sinks easily for a stable measurement.
The durable silicone cable retains its flexibility even under widely varying temperatures, while the corrosion-resistant AISI 316 stainless steel construction of the probe ensures long-term performance. This instrument also serves as a valuable tool for control within HACCP (Hazard Analysis Critical Control Point) analysis protocols.
