Product information "Kern PWS 800-2 precision balance 820 g / 0.01 g"
The Kern PWS is a precision balance with housing and weighing plate made of stainless steel and degree of protection IP65. It is intended for workstations where dust or splashing water occurs. Three models are available: the PWS 800-2 weighs up to 820 g at 0.01 g, the PWS 3000-1 up to 3,200 g and the PWS 8000-1 up to 8,200 g, both at 0.1 g. The tuning fork weighing system has a stabilisation time of 3 s on all three models.
IP65 and stainless steel
The complete device has dust and splash protection to IP65 (EN 60529). The housing and weighing plate are made of stainless steel. According to Kern, the surfaces are smooth and easy to clean. The housing measures 310 x 205 x 85 mm; when fully assembled, the dimensions are 320 x 205 x 90 mm. The balance weighs approximately 3.0 kg. The spirit level and adjustable feet are used for levelling. The ambient temperature may be between 10 °C and 30 °C, the humidity up to 80 %.
Features
The PWS counts pieces with the reference piece counts 5, 10, 30 and 100, determines percentages and density and weighs with tolerance range (checkweighing) with an audible and a visual signal. Under unstable weighing conditions, the averaging function forms an average. Taring is possible manually and several times. The LCD has 16.5 mm high digits; according to the data sheet, operation is via a symbol language. The units can be switched between, including kg, g, ct, lb and oz.
Adjustment, interface and power supply
The PWS is adjusted using an external weight. This does not replace a calibration certificate, which is available separately (see below). An RS-232 interface for connecting a printer is fitted as standard. The plug-in mains adaptor operates at 100 V to 240 V AC at 50 / 60 Hz and 0.3 A and comes with country adaptors for EU, AUS, UK, US and CH. The balance is prepared for battery operation. In battery operation, the balance switches off automatically after 3 min. The battery holder is available as an accessory.
Typical applications
- Environmental technology: weighing samples in damp or dusty environments
- Water analysis: weighing at workstations exposed to splashing water
- Agricultural industry: weighing and counting samples and containers
- Cosmetics industry: weighing and density determination
- Food industry: weighing and portioning at workstations that are cleaned
The PWS 800-2 is the model for weighing in up to 820 g at 0.01 g. The PWS 3000-1 and PWS 8000-1 both read to 0.1 g and have the same weighing pan of 190 x 190 mm; they differ in their weighing range.
