The Hanna Instruments HI 98160 is a waterproof portable pH, oxygen reduction potential (ORP)/mV, and temperature meter with five-point calibration, calibration alerts, a multilevel LCD screen with onscreen tutorial, a polyetherimide (PEI) body pH electrode, a separate stainless steel temperature probe, and stores up to 500 records. A pH meter is commonly used to measure the pH of substance such as water, food, beer, or wine in laboratory, industrial, and food applications. The multilevel backlit LCD screen simultaneously displays the measurement reading, temperature, and tutorial messages. An auto-end mode ensures readings are taken only when they are stable. A good laboratory practice (GLP) key provides access to comprehensive GLP data and log-on-demand holds up to 500 records. Data can be transferred to a computer with the HI 92000 software (not included) using the USB port (cable not included).This meter has up to five-point calibration with eight memorized pH buffers and two custom pH buffers to provide p...

Manufacturer: PCE Instruments Brand: PCE Instruments Model: PCE-PH20S

The PCE-PH20S pH-Meter for soil has been developed with the purpose of finding an effective method for directly determining the pH value of soil. With the help of this pH-Meter, it is possible to quickly and accurately measure the pH value of soil or a sample taken from the soil. To do this, simply insert the electrode into loose soil and reed the pH value on the digital display. Please, take into account that the first measurement requires that there is humidity in the soil. The device is always pre- calibrated by the manufacturer. The pH Meter can be constantly recalibrated using the calibration solutions that come with the device. Calibration data remains stored in the device even when the batteries have been changed. Technical Spezification Measurement range: 0.00 to 14.00pH Resolution: 0.01pH Accuracy : ±0.07pH (between 5 and 9pH) ±0.1pH (from 4 to 4.9 and 9.1 to 10pH) ±0.2pH (from 1 to 3.9 and 10 to 13pH) Calibration: automatic, depending on the calibration solution pH value of 4...
