Pool Line Thermo Hygrometer with Dewpoint - HI95654

SKU: HI95654 Category Tag

HI95654 is a Pool Line portable thermo hygrometer designed to measure the humidity and dew point of indoor pool areas. Measurements of temperature, relative humidity, and dew point are made easy with the rugged, water-resistant housing of the meter and durable casing of the HI706023 probe. HI95654 features a programmable auto-off function after 8 or 60 minutes, temperature readings in both Celsius and Fahrenheit, and dew point determination.

  • Dew point measurement range
  • ℃/℉ temperature readout
  • 10, 000 hours of continuous use


The HI9565 is a rugged, portable thermohygrometer designed to provide high accuracy temperature, relative humidity (RH), and dew ponit readings under harsh environmental and industrial conditions. The meter offers a vThe HI95654 is a rugged, portable thermo hygrometer designed to provide high accuracy temperature, relative humidity (RH), and dew point readings in high humid environments such as swimming pools, hot tubs and spas that are located indoors. The meter offers a variety of features including a HOLD button, Battery Error Prevention System (BEPS), and an adjustable auto-off.

The HI95654 has selectable temperature, RH, and dew point modes. The measurement mode can easily be switched at the press of the RANGE button. Both temperature and RH are measured with the HI706023 probe which features an internal temperature sensor and a built-in microchip that stores calibration data.

Features at a Glance

Durable Humidity Probe – The HI706023 is a thin-film polymer capacitive (TFPC) sensor that accurately measures relative humidity and temperature. Encased in a durable ABS housing, the probe features a perforated cap to allow for rapid and stable measurements. A built-in microchip allows for calibration data to be stored in the sensor as opposed to the meter. If the probe is connected to another hygrometer, the microchip transfers the stored calibration data and eliminates the need to recalibrate the instrument.

℃/°F Readout – Temperature is displayed in ℃ or ℉. A slide switch on the HI95654 allows the user to change the temperature readout unit.

HOLD Button – A simple press of the HOLD button allows the user to freeze a measurement on the LCD screen. Even in HOLD mode, the meter channels can still be scrolled through to show the status of the meter when HOLD was pressed.

Auto-off Feature – The auto-off feature can be programmed to be enabled or disabled. When enabled, the meter automatically turns off after 8 or 60 minutes.
