Weight:
approx. 165 g
Temp. compensation:
Automatic temperature compensation (ATC) in the operating modes "pH", "mV
H
" or "rH"
if temperature probe is used. Compensation temp. range: 0 ... 105°C
If no temp. probe is used, temperature can be entered manually.
If no temp. probe is used, temperature can be entered manually.
pH-calibration:
- 2-point or 3-pt. calibration with standard buffers, DIN-buffers, manually entered puffers
- autom. buffer detection, temperature dependence of standard or DIN buffers will be
automatically compensated
- permissible electrode data:
- autom. buffer detection, temperature dependence of standard or DIN buffers will be
automatically compensated
- permissible electrode data:
asymmetry: ±55 mV
slope: -62...-45 mV/pH
- sensor evaluation according to calibration result (from 10 to 100%).
Rec. redox electrodes:
Reference system: silver/silver chloride, electrolyte: KCl, 3 mol/l
(use only this type if changing values to hydrogen system "mVH" and for rH measurements!)
EMV:
The device corresponds to the essential protection ratings established in the Regula-
tions of the Council for the Approximation of Legislation for the member countries re-
garding electromagnetic compatibility (2004/108/EG).
Additional fault: <1%
