The Model 9.2 Bilirubin Meter uses a GaP Photodiode packaged in hermetically sealed UV glass window cap. Filter used to narrow response as shown on spectral response graph. Applications include monitoring bilirubin light intensity and aging, monitoring blue LED/lamp intensity and aging, monitoring aquarium lamp intensity and aging, monitoring acne lamp intensity and aging, testing eyewear actinic blocking capabilities, and measuring photosynthetic action spectrum blue band. To operate, press and hold push-button switch on face of unit. Aim sensor window in top panel of meter directly at blue 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.

SAMs (Single Analyte Meters): Value and Convenience Single Analyte Meters (SAMs) provide unprecedented economy, simplicity, and accuracy for dedicated photometers. SAMs provide results equivalent to other meters and probes costing much more. SAM (Single-Analyte Photometer) Kit comes in a plastic case and contains everything needed to perform 30 tests: K-7913 Vacu-vials Kit, SAM Photometer, light shield, 4 AAA batteries, screwdriver, and instructions. Methods Because of its strong oxidizing properties, chlorine is an excellent biocide used to treat potable waters, municipal wastes, and swimming pools. When used to treat potable water, chlorine helps alleviate the adverse effects of iron, manganese, ammonia, and sulfide. The Maximum Residual Disinfectant Level for chlorine is 4 mg/L in drinking water. The DPD Method References: USEPA Methods for Chemical Analysis of Water and Wastes, Method 330.5 (1983). APHA Standard Methods, 21st ed., Method 4500-Cl G (2005). In the USEPA-approved DPD methodology, free chlorine reacts with DPD to form a pink product. When ammonia or amines are present, some of the chlorine may exist as combined chlorine. Combined chlorine will not interfere with the free chlorine results, provided the readings are taken at one minute. To determine total chlorine (the sum of free and combined), use the A-2500 Activator Solution (potassium iodide) supplied in the kit. Results are expressed as ppm (mg/L) Cl2.

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI93751-01

The Hanna Instruments 93751-01 sulfate reagent, for use with the HI 96751 Sulfate Portable Photometer, contains the proper dosage for 100 tests that measure the sulfate content using the turbidimetric method in water samples in the 0 to 150 mg/L range. HI 96751-01 contains 100 odorless, white powder sulfate reagent packets, for 100 tests. A reaction between the reagent and sulfate in a sample causes a distinct white cloudiness to appear, which is measured by the meter. 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.
