HI-99141 Boiler and cooling tower pH meter
The HI-99141 is a tough waterproof portable pH meter specifically designed for boiler and cooling tower applications. The meter is supplied complete with a unique pH electrode which features a flat measurement tip and a tough stainless steel almost unbreakable body. The electrode also features an annular Teflon junction for maximum surface contact giving increased response time and greater stability of measurement.
Another feature of the electrode is that it includes a temperature sensor located at the pH measurement point. This means that all pH readings are automatically temperature compensated and that there is no need for a separate temperature probe.
The meter itself shows the pH value with simultaneous temperature readout. pH calibration is automatic with automatic buffer recognition and graphic icons guide the user through the procedure to make things even easier.

HI-83205-02 Photometer for Boilers/Cooling Towers
The HI-205-02 presents engineers and maintenance personnel with an innovative and cost-effective way to monitor boilers and cooling towers. With just one unit, technicians can keep an eye on 24 parameters needed for proper and efficient functioning of their systems. The parameters that can be monitored include: iron, whose presence can be an important indication of corrosion; chlorine to circumvent microbiological fouling; dissolved oxygen, whose presence causes corrosion; silica can point to a contamination of the feed water while phosphate is important to reduce scaling.
These and many other vital parameters can now be measured with just one unit at a cost-per-test that is comparable with chemical test kits.The HI-83205-02 measures Aluminium, Ammonia, Bromine, Chlorine Dioxide, Chlorine, Chromium, Copper, Hydrazine, Iron, Molybdenum, Nitrate, Nitrite, DO, pH, Phosphate, Silica and Zinc.
The HI-83205-02 is supplied complete with 2 cuvets, bottle for D.O.test, batteries, 12 vdc adaptor and instructions.
