Accurate, economical, handheld instrument
The YSI EcoSense® instruments provide accurate data in the most affordable format. The “M” stands for memory and the instruments feature a real-time clock, larger memory and simple data transfer to a PC with a built-in USB port.
The pH100M is easy-to-use, field-worthy and provides accurate and repeatable measurements.
The pH100M measures pH, mV/ORP and temperature with the following features:
- Rugged, waterproof, field-worthy case. IP-67 rated.
- Waterproof micro-USB port for transferring data to PC; no software required.
- Holds 250 data sets; no need to write down data.
- Real-time clock for date/time stamp of saved data.
- User-selectable re-calibration prompt provides reminder to calibrate.
- Automatic buffer recognition (US or NIST buffer sets).
- Automatic or manual temperature compensation.
- 1-year instrument warranty; 6-month electrode warranty.
- 1 and 4-meter field cables available; lab pH and ORP electrodes available.
- Displays electrode efficiency.
- Autolock mode holds stable readings on display.
The pH100M is designed for quick, accurate measurements in an economical platform. Easy-to-use, waterproof and backed by a 1-year warranty, the pH100M is ideal for a wide range of applications.
