Anyone who has ever worked in a factory has worn safety glasses, but there is a difference between simple safety glasses and ballistic shooting glasses. Safety glasses are designed to stop debris from getting into your eyes. Ballistic glasses have met the military requirement for ballistic resistance testing and the ANSI requirement for high velocity impacts. Many companies such as make both types of glasses, but don’t simply search for the term “ballistic.” Many shops sells 77 different types of “safety glasses” in addition to “tactical spectacles,” but many of their glasses meet and exceed U.S. military and NATO specifications for ballistic resistance, even though they don’t have the word ‘ballistic’ in the name. When you head to the range and practice your shooting skills, it is appropriate to use and have safety equipment or protective safety gear, which basically means eye and hearing. But saying you need eye and ear protection is like saying you need shoes, and there’s a big difference between steel-toed hiking boots and strapless pumps with five-inch heels. Since we’re talking about shooting that means eyeglasses that wrap around or protect your eyes from the side as well, as ricochets happen.
Hearing protection is another must have in your list of safety gear, and when it comes to reducing abuse to your eardrums, you have two options — plugs or muffs. Both have advantages and disadvantages, and all plugs and muffs have specific noise reduction ratings (NRRs).
Water quality instruments like the checker is a multi-parameter portable field instrument which measures up to 11 available simultaneous water quality parameters. This advanced technology allows for a highly compact, high performance probe which can measure pH, Temperature, Dissolved Oxygen, Turbidity, Conductivity, and Salinity. The sensor can be used as a remote data logger / Sonde for up to 35 days of monitoring at 15 minute intervals. The standard probe design, with a 45mm (less than 2 inch) outer diameter, can provide measurement of 17 available parameters. The instrument also features an interface port for connection to a global positioning system (GPS), Local area network (LAN), printer, or PC interface via standard RS-232. The new WQC-log software control package allows for data transfer and control with a PC in a standard spreadsheet configuration.
A liquid particle counter calibrator is an instrument that detects and counts particles. Liquid particle counter are specifically working on light scattering or light obscuration or direct imaging. A light source (typically a laser light) is used to illuminate the particle as it passes through the sensor orifice. As the Particle passes through the laser light it scattered or Block light. Direct Imaging based particle counter are absolute in the Market & are not advisable. If light scattering is used, then the redirected light is detected by a photo detector. If light blocking (obscuration) is used the loss of light is detected by a photo detector. The amplitude of the light scattered or light blocked is measured and the particle is counted and tabulated into standardized counting bins.
The Accuracy in particle count is also a very important parameter while doing particle count of your oil .Accuracy of oil Particle counting result is depend on its sensor cell design. There are two kind of sensor used in particle counter. Volumetric Sensor Cell Design Non Volumetric or In situ Sensor Cell Design. Volumetric Sensor cell Design guarantees the 100 % sampling of your oil as complete samples passes through the Laser Diode & Non Volumetric Sensor cell design lead to average of particle counting in your sample.
