EcoSense® pH100M pH/ORP/mV/Temperature

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.
