The Model 8.0 UVC Meter uses a Silicon Carbide (SIC) Photodiode packaged in hermetically sealed UV glass window cap. Interference filter blocks UVA and UVB from response as show on Spectral Sensitivity Graph. Applications include monitoring germicidal lamp UVC intensity and aging , testing eyewear UV blocking capabilities, and testing germicidal lamp fixture leakage. To operate, press and hold push-button switch on face of unit. Aim sensor window in top panel of meter directly at UV source. Note reading on LCD and record if desired. Battery operation voltage is 9V down to 6.5V. Below 6.5V the LCD numbers will begin to dim, indicating the need for battery replacement. Under "typical" service load, the battery should last about 2 years.

Manufacturer: Solarmeter Brand: Solar Light Company, Inc Model: Solarmeter Model 4.0 Color: Light Green

The Model 4.0 UVA Meter's sensor consists of a GaAsP photodiode and a UV filter. It is completely insensitive to visible light longer than 400nm and infrared radiation because its spectral response only covers the UVA region from 320-400nm. Applications include monitoring UV lamp intensity and aging, measuring outdoor UVA, testing acrylic shield transmission, testing window film/transmission, and testing eyewear UVA blocking capabilities. To operate your Solarmeter, aim the sensor window located on the top panel of the meter directly at a UV source. Press and hold the push-button switch on the face of the meter. For best results take note of the distance the reading was taken from the UV source in order to ensure repeatable results. Battery operation voltage is viable from 9V down to 6.5V. Below 6.5V the numbers on the LCD display will begin to dim indicating the need for battery replacement. Under typical service load a standard 9V battery will last approximately 2 years.

Manufacturer: Solarmeter Brand: Solar Light Company, Inc Model: Solarmeter Model 6.5 Color: Red/Yellow

The Model 6.5 UV Index Meter uses a Silicon Carbide (SiC) Photodiode under a hermetically sealed UV glass window cap with Eeff (erythemally effective) filter and diffuser. Applications include monitoring instantaneous UV index measurement, UV index comparison, monitoring reptile lamp intensity and aging, monitoring uv lamp intensity and aging, and UV index tracking over time. To operate, press and hold push-button switch on face of unit. Aim sensor window in top panel of meter directly at UV source. Note reading on LCD and record if desired. Battery operation voltage is 9V down to 6.5V. Below 6.5V the LCD numbers will begin to dim, indicating the need for battery replacement. Under "typical" service load, the battery should last approximately 2 years.

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96706C

Phosphorous portable photometer kit. Kit includes photometer, 2 sample cuvettes with caps, 9V battery, scissors, cloth for wiping cuvettes, instrument quality certificate, instruction manual and rigid carrying case. The HI96706 uses an exclusive positive-locking system to ensure that the cuvette is in the same place every time it is placed into the measurement cell. This measures the phosphorus content in water samples in the 0.0 - 15.0 milligrams per liter (ppm) range. Phosphorus is found in nature as phosphates. Its concentration in water is monitored because it causes corrosion when present in high levels. It is also an essential parameter for the growth of microorganisms and algae, which are often unwanted in tanks and reserves of water. Phosphorus is also an essential element for plant growth and for this reason, is needed in large amounts. It is supplied with 2 sample cuvettes with caps, 9V battery and instruction manual. 0.01 milligrams per liter (ppm) resolution. +/-0.03 milligrams per liter (ppm) +/-4 percent of reading at 25 degree C accuracy. Tungsten lamp. Silicon photocell with narrow band interference filter at 525nm light detector. 0 To 50 degree C (32 to 122 degree F); RH maximum 95 percent non-condensing environment. 9V Battery power supply. Auto-Shut off: after 10 minutes of non-use in measuring mode; after 1 hour of non-use in calibration mode; with last reading reminder. Amino acid method, adapted from standard method for the examination of water and wastewater.

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96762C

Low Range Free Chlorine portable photometer kit. These meters use an exclusive positive-locking system to ensure that the cuvette is in the same place every time it is placed into the measurement cell. Chlorine is widely used in making many everyday products, but most notably, it is used for producing safe drinking water the world over. Even the smallest water supplies are now usually chlorinated. It is also extensively used in the production of paper products, dyestuffs, textiles, petroleum products, medicines, antiseptics, insecticides, food, solvents, paints, plastics, and many other consumer products. Most of the chlorine produced is used in the manufacture of chlorinated compounds for sanitation, pulp bleaching, disinfectants, and textile processing. Organic chemistry demands much from chlorine, both as an oxidizing agent and in substitution, since it often brings many desired properties in an organic compound when substituted for hydrogen, as in one form of synthetic rubber. HI96762C includes photometer, 2 sample cuvettes with caps, 9V battery, scissors, cloth for wiping cuvettes, instrument quality certificate, instruction manual and rigid carrying case. 0.000 to 0.500 milligrams per liter range. 0.001 milligrams per liter resolution. +/-0.020 milligrams per liter +/-3 percent of reading at 25 degree C accuracy.
