Product information "Pool Line pH & Temperature Pocket Tester with 0.1 pH Resolution"

HI981074 Pool Line pH and temperature meter is made for measuring the pH of swimming pool, hot tub, or spa water. This modern looking meter is only 0.7" thick and extremely ergonomic, fitting comfortably in your hand. This tester keeps things simple with a two-button operation; one for ON/OFF, the other for Calibration.

  • Waterproof
  • Automatic calibration
  • Displays pH and Temperature Simultaneously


HI981074 Pool Line waterproof tester features a large multi level LCD which displays both pH and temperature readings simultaneously. The pH readings are displayed with a 0.1 pH resolution and with an accuracy of ±0.1 pH. The pH range of the HI981074 is from 0.0 to 14.0 pH. An exposed temperature sensor allows for rapid automatic temperature compensated pH measurements. Temperature can be set to display in oC or oF. The LCD screen has stability and calibration tag indicators. The battery percent level is displayed at start up alerting the user to the remaining battery power that is available.

Calibration is performed by pressing the dedicated calibration button. Once in calibration mode the pH electrode can be calibrated to 1 or 2 points using the pre-programmed standard buffers (pH 4.01, 7.01,10.01). When the standard value is recognized and stability is reached, the meter automatically accepts and stores the calibration value.

HI981074 is ideal for checking the pH levels of swimming pools, hot tubs, and spas. The accurate reading of pH is critical to ensure that the chlorine is predominately in the hypochlorous acid form instead of the hypochlorite form, which is less effective at killing bacteria. The ideal pH for a pool is between 7.2 and 7.4.

Features at-a-glance


Slim, Ergonomic Design

  • With rounded edges and a case that is only 17 mm (0.7”) thick, the HI981074 is thin and fits comfortably in the hand or pocket.

  • Temperature displayed in oC or oF along with pH


Automatic Calibration

  • Automatic calibration to one or two points using standard buffers (pH 4.01, 7.01 and 10.01).


Stability Indicator

  • A clock tag stability indicator will disappear to alert the user when the reading is stable



  • User-selectable time until meter shuts off to conserve battery life. Options are 8 min, 60 min or disabled.


Low Battery Indicator
