supplied accessories.
PRELIMINARY EXAMINATIONGENERAL DESCRIPTION and INTENDED USE
HI9814 is a durable, portable pH, conductivity, total dissolved
solids and temperature meter for most measurements
encountered in hydroponics, aquaponics or general
agriculture applications. All operations and settings, are
made through only two buttons. The housing is water‑
proof and rated for IP67 conditions.
The supplied HI1285‑7 multiparameter probe measures pH,
EC/TDS, and temperature in one convenient, rugged probe.
A preamplifier is integrated into the probe to protect the
pH measurement from transient electrical noise. Sources
of electrical noise include ballasts used in lighting and
pumps to circulate water and nutrient solutions. Other
user‑selectable features include selectable TDS factors
of 0.5 and 0.7 as well as auto‑off after 8 minutes or
60 minutes to prolong battery life.
