YSI EcoSense pH100A

Handheld pH Meter

YSI EcoSense pH100A - Handheld pH Meter

The EcoSense pH100A is an economical, accurate, and versatile handheld pH meter featuring either automatic or manual temperature compensation and optional probes for mV measurement, peircing applications, or soil slurry sampling.

The pH100A has been updated with many new features including memory for storing up to 50 readings, a waterproof and ergonimical IP67 rated housing, and increased battery efficiency with up to 1000 hours of runtime from a single 9V alkaline battery.

The pH100A handheld pH meter from YSI's line of accurate, durable, and economical instruments features detachable cable and probe assemblies with multiple options providing a versatile and cost effective solution for pH or mV and temperature measurements.

The pH100A is the suggested replacement for the pH100.

Calibration consists of a simple 2 point process with automatic buffer recognition and the ability to display the efficiency of the electrode. Temperature compensation can be performed automatically when used with a combination probe or a seperate temperature probe. Manual temperature compensation is also possible in the absence of a temperature probe. The EcoSense pH100A is very easy to use due to its large LCD display and autolock measurement mode which automatically locks measurements as soon as they become stabile providing consistent results.

The EcoSense pH100A has a pH range of -2 to 16 at a resolution of 0.01 with an accuracy of 0.1 %. When a mV probe is connected the range is -1999 to 1999 mV with a resolution of 1 mV and a 0.1 % accuracy. Temperature readings are accurate to within 0.6 °F. Combination probes, containing both a pH or mV probe and a temperature probe, are waterproof for field use and available in lengths of 1 or 4 meters. Lab cables for pH or mV come in 1 meter lengths. The peircing pH probe features a sharp tip and is useful in many applications like measurements in cheese or grapes. A flat glass probe is also available for taking measurements in soil slurries. All non combination probes require a seperate temperature probe, which can be connected to the instrument simultaneously, for automatic temperature compensation. Alternatively, temperature readings can be manually entered. All probes are single junction with the exception of the peircing and flat glass probes which are double junction.

The pH100A features a water proof IP67 rated enclosure and comes in kits including combination probes and a carrying case or as just the instrument without probes. Calibration data is stored in non volatile memory removing the need to recalibrate after battery replacement. The instrument is powered from a single 9V alkaline battery.

YSI EcoSense pH100A Ordering Instructions

The EcoSense pH100A is available below in complete kits containing the instrument, a field cable with combination pH/temperature probe, and a hard sided carrying case. Alternatively, the instrument can be purchased alone and various cable/probe assemblies purchased separately.

All of the lab grade cable/probe assemblies require the separate purchase of the temperature probe for automatic temperature compensation. Manual temperature compensation is available in the absence of a temperature probe. The temperature probe can be used alone for temperature only measurements if desired.

two specialty probes are available, a piercing probe for measuring cheese, grapes, or any piercing application, and a flat glass probe for soil slurries. All cable and probe assemblies work with both the pH100 and the pH100A.

Also available below are calibration solutions and various accessories.
