Hanna Instruments HI38017 Free and Total Chlorine Low and Medium Range Test Kit with Checker Disc, For 200 Tests
Manufacturer: Hanna Instruments
Brand: Hanna Instruments
Free chlorine reacts with ammonium ions and organic compounds to form chlorine compounds resulting in diminished disinfecting capabilities compared with free chlorine. These chlorine compounds together with chloramines form combined chlorine. Combined chlorine and excess free chlorine together result in total chlorine. While free chlorine has a much higher disinfectant potential, combined chlorine has a much higher stability and has a lesser volatility. There should be sufficient levels of unreacted free chlorine for adequate disinfection, but not so much as to become harmful. Chemical method: DPD. 200 Tests.

Solarmeter Model 9.6 Red Light Meter - Measures from 577-661nm with range from 0-199.9 mW/cmÂ² Red Light
Brand: Solar Light Company, Inc
Model: Solarmeter Model 9.6
The Model 9.6 Red Light Meter uses a GaAsP Photodiode packaged in hermetically sealed glass window cap. Filter used to narrow bandwidth as shown on spectral response graph. Applications include monitoring red LED/lamp intensity and aging, monitoring red fluorescent and HID lamp intensity and aging, monitoring collagen stimulation and wound healing lamp intensity and aging, measuring outdoor red light, and measuring photosynthetic action spectrum red band. To operate, press and hold push-button switch on face of unit. Aim sensor window in top panel of meter directly at red light 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.
This tiny laser power meter is less than Â¾" thick, weighing less than 4 oz. (120 g) and is easily carried in a shirt pocket. Ideal for in the field testing and repair of DVD, VCD, CD and MD (mini disk) players. The controls, display and sensor are all neatly contained and protected within the folding case with directions printed right inside the cover. When open the sensor may be extended for remote use or snaps into a fixed position atop the case. Unit features min/max, bar graph display, auto power off, and hold functions and indicates low battery and over range. Reads in mW and uW. Powered by 2 button cell batteries (included). Operating temperature is 0 ~ 40Â°C, with an operating RH of 80% non-condensing, maximum.
Foot Candle/Lux Meter that features accurate light level measurements plus analog output for capturing readings to a recorder. This Product is NIST Certified which indicates that the product is traceable to standards provided by the National Institute of Standards and Technology (NIST).
Hanna Instruments Potassium, 0.0 to 50.0 mg/L, Turbidimetric Method (300 Tests)
Manufacturer: Hanna Instruments
Brand: Hanna Instruments
The Hanna Instruments 93750-03 potassium reagent, for use with the HI 96750 Potassium Portable Photometer, contains the proper dosage for 300 tests that use the turbidimetric method to measure the potassium content in water samples in the 0.0 to 50.0 mg/L range. HI 93750-03 contains three bottles of the clear liquid reagent, and 300 packets of the odorless, white powder required for the two-step process. A reaction between the reagents and potassium in a sample causes a distinct white cloudiness to appear, which is measured by the photometer. The photometer uses the tetraphenylborate method. Reagents are used in photometers to measure the light intensity of solutions or surfaces. The reagent is mixed with the sample and placed in the photometer, which then produces a reading. Reagents are commonly used in the water quality, agricultural, and horticultural industries to measure the amount of minerals and chemicals in water samples. Hanna Instruments manufactures analytical instrumentation and supplies, including pH meters, electrodes, chemical reagents, and buffer solutions. The company, founded in 1978 and headquartered in Woonsocket, RI, meets International Organization for Standardization (ISO) 9001 standards. Whatâ€™s in the Box?
