PORTABLE/ BENCHTOP MULTI-PARAMETER INSTRUMENTS
MODEL TPCD 27

  • ·pH
  • ·mV
  • ·Ion
  • ·Conductivity
  • ·Dissolved oxygen
  • ·Temperature

COMMON FEATURES:

pH. 

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.

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. 

Conductivity

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.

Temperature

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

  • ·Inputs

One common input for all ranges + corresponding reference input.
Reference input for special applications.
Separate input for a Pt1000 automatic temperature probe.
Low voltage DC input for e.g. a mains adaptor. 

  • ·Outputs 

Galvanically isolated USB communication port for connection to a computer. 

  • ·GLP 

All procedures for a Good Laboratory Practice are on board. 

  • ·Data-logging 

Stores up to 12000 data sets can be stored manually or at a programmable interval.
Allows to mix data from all ranges in the same table.
A powerful data acquisition software enables to view, store and edit the measurements in your computer. 

  • ·Cabinet 

Robust dust and splash-proof cabinet. 

  • ·Special features 

Calibration reminder 0…999 h.
Programmable identification number for use with a printer or computer.
Password protection prevents any unauthorised access to the instrument.
Two-way communication with a printer or computer using USB.
Mains and rechargeable battery operation with programmable automatic switch-off.
Shows percentage of remaining battery capacity.
Optional 12V car adaptor.
