Key pH features:

Key conductivity features:

- Six-point calibration—choose USA, NIST, DIN, or

custom buffer sets

- Auto buffer calibration which automatically

identifies the correct pH buffer for rapid
calibration

- mV offset for calibration to ORP standards,

zeroing mV value, and pH diagnostics

- Compatible with pH and ISE electrodes having

a BNC connector

- Auto-range conductivity from 0 to 199.9 mS in

five ranges with up to five calibration points

- Selectable cell constant of 0.1, 1.0, or 10 from

two-cell probe

- Selectable temperature coefficient; adjustable

from 0 to 10% per °C for accurate compensation
of almost any solution

- Conductivity-to-TDS factor is adjustable from

0.4 to 1.0
