Thermo Scientific Optical Filter with 405 nm Wavelength.

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: HI96785

The HI 96785 portable microprocessor analyzer measures the percent light transmittance of honey compared to analytical reagent grade glycerol. The transmittance value allows identification of the honey Pfund grade. The instrument directly displays the measurement result expressed in mm Pfund. Measurements are made using matched square optical cuvettes having a 10 mm light path. The color of honey tends to darken with age or change according to the method of conservation or production used by beekeepers, (for example: the use of old beehives, contact with metals, the temperature of conservation, exposure to light, etc.). The classes of color are expressed in millimeters (mm) on the pfund scale, compared to an analytical standard scale of reference on the graduation of glycerin. HI 96785 is supplied with sample cuvettes (5), 9V battery, light shield cap, 30 ml bottle of glycerol, instruction manual. 0 to 150 mm Pfund range. 1 mm Pfund resolution. +/-2 mm Pfund at the rate of 80mm Pfund at the rate of 25 degree C accuracy. Light source: tungsten lamps. Light detector: silicon photocells with narrow band interference filter at the rate of 420 nm and 525 nm. Power supply: 9v battery. Auto-off: after ten minutes of non-use in measurement mode; after one hour of non-use in calibration mode; with last reading reminder. Environment: 0 to 50 degree C (32 to 122 degree F); RH max 95 percent non-condensing. Measures 7-19/32" length by 4-3/32" width by 2-11/16" height. Weight: 12.7 oz. Direct measure method.

Cyanuric acid and pH chlorine portable photometer kit. Legionella species is the agent that causes human legionnaires' disease as well as the lesser form, pontiac fever. Transmission is facilitated by the inhalation of mist droplets containing the Legionella bacteria. Common sources of Legionella include cooling towers used in industrial cooling water systems as well as in large central air conditioning systems, domestic hot water systems, fountains, and similar disseminators that draw from a public water supply. Natural sources include freshwater ponds and creeks. Since Legionella is especially harmful to people with weakened immune systems, it should be actively checked for in the water systems of hospitals and nursing homes. HI96725C includes cyanuric acid and pH chlorine photometer, hard carrying case, 2 sample cuvettes, scissors, cuvette cleaning cloth, battery and instruction manual. 0.00 to 5.00 milligrams per liter (ppm) free Cl, 0.00 to 5.00 milligrams per liter (ppm) total Cl, 0 to 80 milligrams per liter (ppm) CYA, 6.5 to 8.5 pH range. 0.01 milligrams per liter free Cl, 0.01 milligrams per liter total Cl, 1 milligrams per liter (ppm) CYA, 0.1 pH resolution. +/-0.03 milligrams per liter +/-3 percent of reading free Cl, +/-0.03 milligrams per liter +/-3 percent of reading total Cl, +/-1 milligrams per liter +/-15 percent of reading CYA, +/-0.1 pH at 25 degree C accuracy. Tungsten lamp. Silicon photocell with narrow band interference filter at 525nm light detector. 9V battery power supply. 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. Chlorine method, adaptation of the EPA recommended DPD method 330.5. CYA method, adaptation of the turbidimetric method. pH method, phenol red method.

Uncalibrated Diffuse Reflectance Standard, 2" - 99% Spectralon Diffuse Reflectance Standards can offer the highest diffuse reflectance values of any known substance. These durable, chemically inert standards can have typical reflectance values ranging from 2% to 99% and are spectrally flat over the UV-VIS-NIR spectrum. All Spectralon materials are optically flat to +/- 4% over the range of 250 - 2500 nm and +/- 1% over the photopic region of the spectrum. Spectralon Diffuse Reflectance Standards are highly Lambertian, with Spectralon SRM-99 reflectance material being the most Lambertian reflector available for use over the wavelength range from 250 - 2500 nm.

Nitrogen, phosphorus, and potassium (NPK) are often the first three factors considered when making recommendations to growers. Compared to the HI 83215, the HI 83225 provides control over three additional important growing factors: sulfur (most common as sulfates), calcium and magnesium. HI 83225 is designed for the hydroponics and greenhouse industries to measure seven nutrients commonly present in fertilizer enriched solutions. It can measure fifteen different methods using specific liquid or powder reagents, and has four measuring channels for a wide range of tests. The optical system of HI 83225 is based on special subminiature tungsten lamps and narrow-band interference filters to guarantee both high performance and reliable results.

For use with eXact Photometers, the eXact Strip Micro Chloride/ Salt III incorporates the patented eXact reagent delivery system created by Industrial Test Systems, Inc. which is ideal for technical and non-technical users. By dipping the eXact strip into a photometer cell, the exact amount of reagent is released into the water causing a change in color or turbidity. The change is measured by an eXact photometer giving the user fast and accurate results. Each unit consists of a bulk bottle of 25 tests.
