1 ANALYTICAL INSTRUMENTS analytical instruments & pocket-sized testers ETI offers a comprehensive of analytical meters including ph, conductivity and dissolved oxygen meters. These instruments are designed as portable laboratory analysis testers for use in a wide of industries. applications These analytical meters can be used in many areas, for example: hydroponics food production water quality process industry laboratories fish farming aquariums agriculture ph meters The ph (potential hydrogen) level of any material or substance is defined by the acidity or alkalinity of that substance and is represented on a scale of 0 to 14; 7pH being neutral, 0pH acidic and 14pH alkaline. This factor can affect many parameters in nearly all types of process or production. acid alkaline 0pH 7pH 14pH TDS meters Conductivity and TDS meters are most commonly used to measure the concentration of dissolved solids in liquids. Conductivity meters utilise a substance's ability to conduct an electric current to give a reading in microsiemens (:S) or milli- Siemens (ms). Some TDS instruments automatically convert the conductivity value into parts per million (ppm) thus providing a direct reading of the dissolved solids concentration. Redox meters Redox meters are similar to the ph meters that quantify acidic or alkaline solutions. Liquids can also be graded as oxidising or reducing based on Redox measurements, sometimes referred to as ORP (oxidation reduction potential). Oxidation is a process during which a molecule or ion loses electrons. Redox meters are used to monitor many processes, particularly those involving reversible actions. dissolved oxygen meters Dissolved oxygen meters are used to determine the quantity of dissolved oxygen in liquids, primarily water. The instruments give a reading/measurement in parts per million (ppm). The quantity of dissolved oxygen in water is a good indicator of water quality serving industry for 25 years

The unit allows the user to monitor light intensity and levels in a 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 until the lamps require replacing. The light meter measures both Lux or footcandles (FC) over the of 0 to 50,000 Lux/foot-candles. The correct level of light is imperative in a wide 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 Lux & FC light meter specification 1301 light meter 0 to 50,000 Lux/FC resolution 0.1/1/10/100 Lux/FC ±5% or ±10% > 10,000 Lux/FC 12 volt MN21 life 100 hours 12.7mm LCD 25 x 64 x 188mm 160 grams MEASUREMENT THAT WORKS tel:
