GENERAL DESCRIPTION
HI 981504 has been designed for continuously and simulta-
neously monitoring pH, TDS and temperature.
Simply install the HI 981504 above the sample to be tested,
plug the instrument to the mains and immerse the probes.
pH, TDS and temperature measurements will be simultaneously
displayed on three backlit LCDs.
The user can easily select the temperature unit (°C or °F)
through a switch on the rear panel.
The HI 1286 gel-filled pH electrode is provided with a water-
proof sheath to protect the BNC connector. The unique design of
the electrode provides longer life even in aggressive solutions.
The HI 7634 TDS probe is easy to clean and requires little
maintenance.
Measurements are accurate and the meter can be calibrated at
one or two points for pH, and at a single point for TDS.
Temperature range is factory calibrated.
Two models are available:
• HI 981504/5 with 0.5 TDS factor
• HI 981504/7 with 0.7 TDS factor
1. Backlit LCD for pH readings
2. pH calibration trimmers
3. Backlit LCD for TDS readings
4. TDS calibration trimmer
5. Backlit LCD for temperature readings
6. BNC connector (pH electrode)
7. Protective sheath for BNC connector

Recommendations for Users
Before using these products, make sure that they are entirely suitable for the environment in
which it is used. Operation of these instruments in residential areas could cause unacceptable
interferences to radio and TV equipment. The glass bulb at the end of the electrode is
sensitive to electrostatic discharges. Avoid touching the bulb at all times. During operation,
ESD wrist straps should be worn to avoid possible damage to the electrode by electrostatic
discharges. Any variation introduced by the user to the supplied equipment may degrade the
instruments’ EMC performance. To avoid electrical shock, do not use this instrument when
voltage at the measurement surface exceeds 24 Vac or 60 Vdc. To avoid damage or burns, do
not perform any measurement in microwave ovens.
