Microbe_SensorBioSentinel Microbe SensorKanomax

Model 3070

The BioSentinel microbe sensor from Kanomax can detect microbes such as fungi and bacteria in as little as 10 minutes. Using a patented heating system that serves as a catalyst to enhance the auto-fluorescing properties of these biological particles, the BioSentinel is able to detect them in real-time, providing early warning of a breach in the controlled environment and making it easier to pinpoint the source.

  • Real-time measurement of microbes (in just 10 minutes)
  • No special skill required to operate the sensor
  • Light weight and compact
  • Applications include: pharmaceutical, cosmetic, food and beverage production facilities; medical facilities such as exam and patient rooms; cooking and dining facilities

Static Meter

Static Meter

The Model 289 is ideal for those who need to make qualitative static surveys at the most affordable price. It features a high-speed LED bar graph that quickly shows the magnitude and polarity of the static charge. A simple-to-operate zero button and conductive case (for obtaining a ground connection) help to make this one of the easiest instruments you will ever operate.

Ground TestersGround Testers

The Model 275A Ground System Tester measures the resistance of personnel grounding systems (wrist straps and heel straps) and work area grounding systems (table mats and floor mats), and indicates if the resistance is high (open), low (hazard), or within acceptable limits to control damage to sensitive components due to electrostatic discharges. Testing is as easy as pushing the test button and observing the color-coded indicator lights. The safe operating limit can be set at 10M or 100M ohms using a switch on the front of the instrument. The instrument is supplied with a ground cord. An optional leather carrying case is available
