JSA Photonics HH-100B Operating Instructions

HH-100B Portable Electronic Hydrometer
Operating Instructions 05/01/2019
This field instrument is based on novel optical technology developed by JSA Photonics and
provides the user with a safe and convenient ability to directly measure the specific gravity (SG)
and the corresponding state-of-charge (SOC) of open port, lead acid batteries. These batteries
are commonly found in starting, lighting and ignition systems, stationary back up battery
systems and motive power applications. It is intended for use by trained professional
maintenance personnel. See disclaimer **below.
On
Introduction
device is used by submerging the active area of the glass probe (about 1") shown above in
This
the battery electrolyte. The active area must be completely submerged. The instrument is self-
calibrating and automatically initiates self calibration mode when the "on" button is pressed. It
is designed to be used at normal room temperature although may be used within the range of
10-30 C without significant impairment of accuracy. Also note that the specific gravity of
battery electrolyte does depend on the temperature and the unit is calibrated at 20 C. Step by
step operation is described below.

Safety Considerations

1. Batteries can be dangerous. They
contain hazardous chemicals and
considerable energy.
2. Battery servicing and testing should
only be done by personnel familiar
with safety and proper safety
equipment.
3. Failure to follow proper handling
procedure may result in serious
personal injury.
4. Contact with battery fluid can cause
severe burns and eye damage. If you
come in contact with the fluid
immediately rinse the area with cold
water and consider consulting a
physician.
5. Do not service batteries near open
flames or electrical sparks. Explosions
may result.
