Manufacturer: Cannon Instrument Brand: CANNON Instrument

Reverse-flow type, for measurement of kinematic viscosity of dark Newtonian liquids according to ASTM D 445 and ISO 3104. Permit measurements of liquids whose meniscus cannot be seen at the timing marks when using Cannon-Fenske Routine-type viscometer. Used to measure kinematic viscosity of liquid (cutback) asphalts and road oils at 60°C (140°F) in range of 30 to 6000 centistokes according to ASTM D 2170. Also used to study lubricating oils at low temperatures when investigating the effect of various additives on lubricating and hydraulic oils. External pressure can be applied to vary shear stress and shear rate. cifications conform to ASTM D 446 and ISO 3105.

Manufacturer: Ade Advanced Optics Brand: Ade Advanced Optics Model: ExtGemRefra

Measuring Range: 1.30 – 1.81 RI Minimum Graduation (RI): 0.01 RI Illumination: Internal illumination with momentary switch Size: 30mm x 70mm x 130mm Scale Division: 0.01 nD Weight: 0.4 kg Ranges of Application: Laboratory, Gemology Filter: Polarizing filter Made of durable heavy metal and scratch proof glass This item is commonly known as Gemstone Refractometer, is the primary and most powerful tool in identifying and authenticating polished precious and semiprecious gemstones and also observing the optical properties and the structure of gemstones. This model is just as good as the expensive models used in gemological institutes, it has a built-in light source and with the aid of the Contact liquid (RI Fluid), which creates an optical contact between the glass and the gemstone, you can measure or test the Refractive Index of faceted stones, its transparency or opacity, and its beauty, durability and scarcity. The refractive index (RI) of a gemstone provides the single most important piece of information to a gemologist seeking to identify an unknown stone. Due to its chemical composition and crystallization structure, each gem has a typical refractive index. In fact, you can also use this tool to measure R.I. for many minerals in crystal form as long as the crystals have a flat and polished face. Through these parameters, you can determine whether the gem is a Single Refraction (Isotropic) or Double Refraction (Anisotropic or Birefringence).

HemoPoint® H2 DMS Carrying Case, Plastic (Empty)

Manufacturer: Hanna Instruments Brand: Hanna Instruments Model: BL983318-0

BL 983318 is a mini controller that has been designed for easy, affordable installation in tight spaces, ideal for simple yet effective process control. Features ATC (Automatic Temperature Compensation) and simple one point calibration performed through the trimmer. The multicolored LED continuously indicates if the controller is in measurement, dosing or alarm mode. Wiring and external device connections are extremely simple to perform through the terminals on the rear of the instrument. Manual control is particularly useful during maintenance operations, because it permits operators to enable or disable the dosing relay according to need. The overtime control system advises users when the relay is active too long, helping to prevent over-dosage. This model is supplied with mounting brackets, transparent cover and instruction manual. Range: 0.00 - 10.00 ppt. Resolution: 0.1 ppt (10 ppm). 0.5 TDS conversion factor. Accuracy at 25 degree C: +/-2 percent F.S. Calibration: manual with CAL trimmer. Temperature compensation: automatic, 5 to 50 degree C (41 - 122 degree F) with Beta =2 percent/degree C. 12Vdc Power supply. Dosing relay: maximum 2A (fuse protected), 250VAC, 30 Vdc. Setpoint: adjustable from 0 to 10 ppt (10000 ppm). Overtime: adjustable, typically from 5 to approx. 30 minutes. Measures 3-3/32" length by 1-57/64" width by 3-11/16" height.
