In domestic water, iron can alter the taste and make it unpleasant to drink. It can also stain laundry, damage kitchenwares and favor the growth of certain bacteria. However, low levels of iron are critical in beverage production. Hardness is a consequence of the type of rock layers which the water passes through and of its permanence in the water bearing stratum. Hardness can cause pipe rusting in water heating and cooling systems, reverse osmosis and demineralization plants. It can also increase the consumption of soaps and detergents in industrial washing machines or laundries. HI96741 can provide critical measurements of low range iron and total hardness (magnesium and calcium). The iron concentration in water needs to be monitored since it can become harmful above certain levels. Hardness, on the other hand, is indicative of the presence of calcium and magnesium in water. By passing through various layers of soil and rocks, rain water dissolves some of the mineral substances. With the portable HI 96741 you can monitor both iron and hardness levels. HI96741 is supplied with 2 sample cuvettes with caps, 9V battery and instruction manual. 0.00 To 4.70 milligrams per liter (ppm) total hardness and 0 to 1.60 milligrams per liter (ppm) iron LR range. 0.01 milligrams per liter total hardness and iron LR resolution. +/-0.11 milligrams per liter +/-5 percent of reading total hardness and +/-0.01 milligrams per liter +/-8 percent of reading iron LR at 25 degree C accuracy. Tungsten lamp. Silicon photocell with narrow band interference filter at 525nm light detector. Auto-off: after ten minutes of non-use in measurement mode, after one hour of non-use in calibration mode with last reading reminder. 0 to 50 degree C (32 to 122 degree F); RH maximum 95 percent non-condensing environment. Measures 7.6" length by 4.1" width by 2.7" height. Adaptation of TPTZ method.

Manufacturer: Aven Brand: Aven Model: 26200B-213

Triple color LED ring light is ideal for applications where you want to create a contrast to enhance a feature of a part. Using color enables you to enhance and see features that would otherwise get washed out with standard white light. The mode function allows you to change from blue to red to white. Brightness control helps provide the correct light intensity for your applications. The LED lights are flicker free, energy efficient and eco friendly and operate at low temperature and do not change color over time. Opening 62mm with three thumb screws for easy mounting. Comes complete with power supply and ring light adapter.

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96715C

The HI 96715C is a medium range, waterproof photometer for measuring ammonia levels in water samples. The meter uses an adaptation of the ASTM Manual of Water and Environmental Technology, D1426-92, Nessler method, and a reaction between the reagent and ammonia in the sample causes a yellow tint. The light source is a light emitting diode, and the light detector is a silicon photocell with narrow band interference filter. A GLP feature indicates when the device was last calibrated and allows the user to restore factory calibration. Range is 0.00 to 9.99 mg/L (ppm) + or - 0.05 mg/L (ppm) or 5% of reading, with resolution 0.01 mg/L (ppm). The device operates on one 9V battery, with an auto-off function after 10 minutes of non-use. Dimensions are 192 x 104 x 69 mm (7.6 x 4.1 x 2.7”) with weight 360 g (12.7 oz.). Reagents are purchased separately. Ammonia is often an indicator of organic decay, and high levels can be harmful to many organisms. Ammonia testers are used to measure ammonia levels in natural, industrial, and waste waters. Hanna Instruments manufactures a wide variety of analytical instrumentation, including pH meters, multi-parameter meters, electrodes, chemical reagents, and buffer solutions.
