The Model 3520 is a fully specified laboratory pH/mV/temperature meter that includes full support for good laboratory practices.
The meter supports 1, 2 and 3 point pH calibration on either manually entered pH buffer values or automatically temperature compensated buffers to DIN, JIS and NIST standards.
Powerful data logging capabilities are included, with the ability to store up to 512 readings either manually, at timed intervals or on alarm events. GLP compliance has also been considered with security code protected user data and calibration data status displays.
