PH meter

PORTABLE pH METER HAS A FULL LAB SPEC

The Micro 500 is an advanced technology pH meter from Palintest that is accurate to one hundredth of a pH unit and offers a full 'laboratory bench' specification from a portable, hand-held package.

This meter combines pH and temperature measurement with a millivolt readout for oxidation-reduction potential and specific ion electrodes.

Easy to set up and maintain, the instrument's on-board microprocessor automates temperature compensation, buffer recognition and calibration against standard buffer solutions. Buffered at the touch of a button, buffer data is stored in memory, even after switch-off.

pH is measured from 0.0 - 14.00 with an accuracy of plus or minus 0.01 pH and a resolution of 0.01 pH. The measurement range for temperature is 0-100蚓, with 0.5蚓 accuracy and 0.1蚓 resolution.

Supplied complete with a tough epoxy-bodied combination pH electrode and separate stainless steel temperature sensor, an oxidation electrode is optional. This meter measures 140 x 47 x 35 mm and weighs 200g. (product code: PT 140)

Conductivity Meter

INGENIOUS, EASY-TO-USE, MULTI-RANGE CONDUCTIVITY METER

A lightweight, multi-range conductivity meter with a vast number of applications, from testing demonized water through to brine. The Micro 500 Conductivity Meter is effective in the routine monitoring of demineralization and other high purity water treatment operations, and in obtaining the general state of a solution's conductivity levels.

The meter is very simple to use. Once turned on, pressing the MODE key selects Conductivity or Temperature. The probe is then dipped into the sample and a reading is provided. It features a large custom LCD for clear and easy reading.

The meter's hard-wearing conductivity probe features an ingenious design which addresses the problems of polarization and contamination that can affect conductivity readings.

The sensor has four steel rings arranged concentrically, one above the other. A voltage is applied to the external rings and this generates an AC current, producing a stray field in the liquid which is then picked up through the internal rings.

The meter measure up to three ranges, from 0 to 199.9 or 1999 microsiemens per cm, or to 19.99 millisiemens per cm, with auto-ranging capability, switching to the appropriate range automatically. It is accurate to ?% of full scale.

It is factory calibrated, but for accuracy the meter can be calibrated independently on each measurement range. Palintest Standard Conductivity solutions are available as accessories for checking the instrument.

The meter has automatic or manual temperature compensation from 0 to 80蚓. It also features a temperature coefficient control which can be set for solutions where the temperature coefficient differs from that of water.
