HI 9033 • HI 9034 - Waterproof, Multi-range EC and TDS Meters with ATC for Field Applications.

HI 9033 and HI 9034 have been proven time and again to hold up under extended use in wet, humid, dusty and muddy conditions. HI 9033 utilizes a single probe to perform all conductivity readings in four ranges. This allows the user to measure samples from deionized water to brine
without having to switch or recalibrate the probe. HI 9034 measures total dissolved solids (TDS) in three ranges to offer the highest accuracy when performing measurements in diverse applications such as HVAC, waste water treatment and reverse osmosis. All three ranges can be activated at the touch of a button without having to change the conductivity probe.

Both meters perform measurements with ATC (automatic temperature compensation) which adjusts for the effects of temperature. These portable instruments also feature BEPS (Battery Error Prevention System) technology that alerts the user when low batteries could affect the readings.

HI 9835 - Waterproof EC/TDS/°C/NaCl Meter for Laboratory and Field Applications

HI 9835 combines four important parameters you need for measuring conductivity. Now you can sample Electro- Conductivity (EC), Total Dissolved Solids (TDS), sodium chloride (NaCl) and temperature simultaneously. HANNA instruments®'s probe design innovation uses 4 rings enhanced with platinum for greater stability while increasing the range of measurable concentrations and temperature. You can choose between automatic and manual temperature compensation to match your operating requirements. In addition, you can also select from a range of TDS factors from 0.40 to 0.80 and a range of temperature coefficients 0.00 to 6.00% for greater consistency and reproducibility. The housing is completely waterproof and
built to survive the harsh conditions of field use. For extended time studies, this meter can be connected to a 12 Vdc power supply (optional).

HI 98360 - Waterproof EC/TDS/NaCl/°C Meter with Auto Endpoint

HI 98360 is a rugged waterproof conductivity meter, which combines versatility and realiability with ease of use. This portable instrument is equipped with an auto-ranging feature and allows the user to measure EC and TDS with the resolution that best fits with the sample. Reference temperature for compensation can be set at 25 or 20°C, as required by the European water analysis regulation for conductivity measurements. All readings can be stored and then transferred to a PC through the RS232 serial port. The "Auto Endpoint" feature makes HI 98360 the ideal meter for field measurements: after entering this mode, the instrument will automatically freeze stable readings on the LCD. The included HI 76309/1.5 probe is a potentiometric 4-ring probe for EC/TDS and temperature measurements. The HI 76309/1.5 features a PVC body, stainless steel sensors and 1.5 m (4.9') screened cable.
