Environmental Monitoring

Ref: ETI 89088
The 89088 mini hand held combined anemometer and thermometer is a general purpose vane air speed meter that simultaneously displays both air flow measurement and temperature. The instrument measures airflow over the range of 1.1 to 20.0 metres per second (60 to 3937 feet per minute) with a resolution of 0.1 metres per second (2 feet per minute) and temperature over the range of 0 to +50°C with a resolution of 0.1°C. The 89088 is housed in a robust ABS case and features a custom LCD display. The instrument is ideal for ventilation surveys, air conditioning, heating and environmental monitoring.

The 8711 therma-hygrometer is an easy to use humidity meter and thermometer. The display incorporates a custom LCD with °C/°F, %rh, max/min and hold indication. There is an automatic display of both open circuit and low battery. The 8711 humidity meter simultaneously displays both the%rh and temperature. The humidity meter measures%rh over the range of 0 to 100%rh with a resolution of 0.1%rh and temperature over the range of 0 to +90°C with a resolution of 0.1°C or °F switchable. An auto power off facility turns the therma-hygrometer off automatically after 20 minutes which maximises battery life. The unit is powered by a 9 volt alkaline PP3 battery with a minimum life expectancy of up to 100 hours, or via a 9/230 volt AC/DC power adaptor for continuous use. The therma-hygrometer incorporates, as standard, a RS232 output socket.

The 1301 light meter is an economical light meter ideal for both the professional and hobbyist. This light meter allows the user to monitor light intensity and levels in a variety of applications. The best way to use a light meter is to measure the light levels when installing new lamps or lighting and then measure the light intensity thereafter on a regular basis until the lamps require replacing. The light meter measures both Lux or footcandles (FC) over the range of 0 to 50,000 Lux/foot-candles. The correct level of light is imperative in a wide range of working environments for safe working and to avoid unnecessary eye strain. The correct level of light is a necessity for plant growth. Sufficient light is needed for photosynthesis to take place so that plants can flower and bear fruit. Commercially, it is important to regularly check artificial lighting levels to ensure healthy plant growth. The lack of adequate light is the most common cause for poor plant growth. As artificial lighting will degrade in intensity with time, it is essential to measure at regular intervals.
