|
HD3405.2 Laboratory
Meter measures pH, Redox potential (ORP) in mV.
The HD3405.2 measures pH, Redox potential (ORP) in mV.
It measures temperature with Pt100 or Pt1000 immersion, penetration or
contact probes.
The pH electrode calibration can be carried out on one, two or three
points and the calibration sequence can be chosen from a list of 13
buffers.
Other common function of this instrument series include: Max, Min and
Avg function, the Auto-HOLD function, the automatic turning off which
can also be disabled.

HD 3405.2 Bench-top pH
meter-Thermometer measures pH, mV, ORP values by pH, Redox, or separated
reference electrodes, temperature by Pt100 or Pt1000 probes. Datalogger
which stores maximum, minimum, average value, RS232 C output for data
transfer in real time to a PC or printer. Functions: REL, HOLD and auto
power off which can be disabled.
Battery power supply or mains power supply by SWD10 (optional). Complete
with 3 batteries, instructions manual, software Deltalog 9 suitable from
version 2.
Electrodes, calibrating solutions, TP47… series temperature
probes with SICRAM module, cables for PC connection and outer power supplier
have to be ordered separately.
