The ETI 1301 is an economical light tester ideal for both the professional and hobbyist. The ETI 1301 allows the user to monitor light intensity and levels in a wide variety of applications. The best way to use a tester is to measure the light levels when installing new lamps or lighting and then measure the light intensity thereafter on a regular basis (monthly or quarterly) until the lamps require replacing.
The ETI 1301 measures both lux or foot-candles over the range of 0 to 50,000 lux/foot candles. The unit is powered by a 12 volt MN21 alkaline battery.
Horticultural & Hydroponics
The correct level of light is a necessity for plant growth. Sufficient light is needed for photosynthesis to take place so plants can flower or bare 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.

1. Large Digital Hygro-Thermometer and Clock (Ref: 100333 A10)

Regular testing is essential to ensure the good quality of water in a swimming pool. The ideal pH for pool water is between 7.2 and 7.6 pH. High levels of total dissolved solids (TDS) may produce cloudy water and cause corrosion, TDS should be kept at under 20ppm (parts per million).

This easy to use pocket-sized 8703 therma-hygrometer measures both % relative humidity and air temperature and additionally calculates dew point.

The digital 8703 therma-hygrometer incorporates a clear LCD display indicating both % RH and temperature simultaneously. The therma-hygrometer measures % RH over the range of 5 to 95% RH with a resolution of 0.1% RH and temperature over the range of -20 to +50°C with a resolution of 0.1°C or °F switchable. The display also automatically indicates both open circuit and low battery, when applicable.

The therma-hygrometer incorporates six easy to use, push button switches, allowing the user to select on/off, °C/°F, max/min, dew point (td), reset (RST) and hold functions.

The 8703 therma-hygrometer is powered by two 1.5 volt alkaline MN2400 (AAA) batteries which allows the unit to operate up to 500 hours or one year. Each 8703 therma-hygrometer is supplied with a sensor protective cover which incorporates a pocket clip.
