General Description & Intended Use
HI981204
is a compact ORP and temperature tester, part
of Hanna Instruments pool-line family. It features a two-
buttons operation system and is easy to use. The compact and
waterproof casing is designed to float if accidentally dropped
in the water. The tester is factory calibrated and measures
temperature in both °C and °F. It displays a stability tag that
will disappear once the reading has stabilized.
Battery level and low-battery indicator are displayed on the
LCD to alert the user in the event that low battery power could
adversely affect the readings.
BEPS (Battery Error Prevention System)
The tester will automatically shut off if there is not enough
power to guarantee an accurate reading.
