ETI MicroTherma 2K Thermometer
The MicroTherma 2K microprocessor based thermometer measures temperature over the range of -200 to +1372°C with a 0.1°C/°F resolution. This MicroTherma 2K thermometer incorporates an easy to read, LCD display with open circuit, low battery, hold, max/min and °C/°F indication.
The MicroTherma 2K thermometers should never need re-calibrating as the built-in microprocessor enables the instruments to continuously and automatically carry out self-diagnostic re-calibration. An additional feature allows the user to adjust the reading (±2.5°C) to offset any probe errors, correcting any inaccuracies of the probe. The thermometer thereafter will automatically store, display the offset and adjust the instrument for the known probe error, maximising system accuracy.
The instrument incorporates the benefit of recording both max and min readings with a reset function. An auto power-off facility maximises the battery life, turning the thermometer off automatically after 30 minutes.

ThermaData™ Loggers meet European standard
BS EN 12830:1999 for temperature recorders
ETI's ThermaData Loggers have been designed by us and tested by an independent test house to ensure they meet BS EN 12830:1999 European standard for temperature recorders for the transport, storage and distribution of chilled, frozen, deep frozen, quick frozen food and ice cream.
This European standard specifies the technical and functional characteristics of air temperature recorders. It also specifies the test methods that allow the determination of the equipment's conformity to suitability and performance requirements.
The lightweight, self-contained, ThermaData Loggers have been designed to meet a variety of applications in both the food and pharmaceutical industries. The loggers are available with or without a LCD display and with or without external probes.

What is pH?
"pH is the Unit of Measure used to express the degree of acidity of a substance.
The centimetre is a unit measure of length. The gram is a unit measure of weight. So, pH is the unit measure we use to say how much acid is in a substance. The pH scale goes from 0 to 14. A pH of 0 means a very high acid activity. Substances such as lemon juice and vinegar are acidic with pH value of 2 to 3. Nitric acid and hydrochloric acid are very strong with pH values of 0, while stomach acid has a pH of 1. Addition of a strong acid, such as sulphuric acid (H2SO4) to water makes the resulting solution very high in active acid cincentration. This is called an acidic solution."
