  • Hanna Continuous pH/TDS/Temp

    The HI 981504 has been designed for continuous and simultaneous monitoring of 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.

    Users can easily select the temperature unit through a switch on the back panel.

    The HI 1286 gel-filled pH electrode is provided with a waterproof sheath to protect the BNC connector. The unique design of the electrode provides longer life 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.

    Note: This meter may not function properly when used around digital ballasts.

  • Hanna Commercial ph/EC/TDS/Temp Meter

    Customers have been asking for a commercial-quality meter instead of the "disposable" meters that have flooded the market during recent years, and BGH is proud present the cream of the crop. The HI 991300 is a commercial-range meter at a near hobby-range price. Key features include electrical shielding (you can now get accurate TDS readings from your reservoir with the water pump running), less frequent calibration, and our personal favorite - like most high-end electrical meters, the electrode is attached to the bottom which makes for easier reads.
