Product Description
One waterproof handheld can cover pH, conductivity, TDS, salinity and resistivity on every field trip. The OHAUS Starter 400M multi-parameter portable meter is robust, lightweight and sealed for prolonged use in wet environments.
This listing is for OHAUS item number 30468990: Starter 400M Portable pH and Conductivity Meter ST400M-B, IP67, Meter Only. It reads -2.00 to 16.00 pH at ±0.01 pH, ±1999 mV, conductivity from 0.01 µS/cm to 199.9 mS/cm, TDS, salinity to 99.9 psu, resistivity to 20 MOhm·cm and -5 to 110 °C. The IP67 housing has a rubber cover, a rechargeable lithium battery provides about 40 hours of use, and 1,000 results transfer over micro-USB. The ST400M-B is meter only, and the ST400M-G includes IP67 ST320 pH and STCON3 conductivity electrodes with 3 m cables. Order it from LIGHT LABS alongside the rest of your OHAUS balances, weights and lab equipment.
