Multi-point (1....5) calibration for more linearity.
Selectable resolution from 0.001 pH to 0.1 pH.
Automatic calibration with any of nine pre-programmed and five user specified pH buffers.
Accepts pH electrodes with any zero point (Eo) between ±999 mV.


Features mV calibration for accurate ORP measurements.
Selectable resolution from 0.1 mV to 1 mV.

Ion ( Only inTMULTI 27)

Direct concentration measurement.
Ion mode is easily calibrated with any two standards and a blank correction.
Useable with Ion Selective Electrodes like F , Cl , NO3, NH3 -, NH4 +, Br-, I-, CN-, Ca++ etc. 


Multi-point (1....3) calibration for more linearity.
Extended conductivity range; to measure the full range from 0.001 μS/cm to 2000 mS/cm requires 3 electrodes: 0.1, 1 and 10 cm-1.
Selectable reference temperature: 20° or 25°C.
Automatically selects correct range and frequency.
Automatic cell constant determination with any of three preprogrammed or user specified standards.
Allows to lock the initial conductivity range to avoid nonlinear titration curves.
Accurate low conductivity measurements by eliminating the capacitive component of the electrode and its cable (avoid the use of long cables!).

Dissolved oxygen(only in TPCD27 & TMULTI 27)

Operates with a galvanic dissolved oxygen electrode requiring no polarisation time and no zero calibration.
Selectable resolution from 0.01 mg/l (0.1%) to 0.1 mg/l (1%).
Manual salinity compensation 0-40 ppt.
Automatic air pressure compensation 600-1300 hPa.


Reads temperatures with 0.1°C resolution.
Manual or automatic temperature compensation.
Calibrates temperature probe for quality measurements.
