ACL-600 human body electrostatic detection instrument electrostatic detector
ACL-600 is a new , unique , intuitive detection means for detecting the amount of electrostatic charge carried by the human body . This device can be easily hung on the wall outside the electrostatic protection areas to avoid static electricity charged by accidentally ran into the protection zone . Staff will also find this device suitable for periodic testing whether they generate static electricity protection zone . ACL-600 can be used to detect the amount of static electricity carried by the body , can also be used to measure the electrostatic potential difference between two people , as well as verification wristbands , winding , grounding plugs , special flooring, coatings, clothes , chairs , etc. are protective active. ACL-600 electrostatic detection table is a reliable , simple and easy to use static indicator , you can protect your valuable equipment from electrostatic hazards , thus saving money. In order to ensure the accuracy of measurement and, more importantly , to enable staff to discharge to safe limits less , ACL-600 must be grounded . Contact measurement , and then observe the liquid crystal display gives the positive and negative poles 0 to 19,990 volts in the electrostatic voltage. The instrument has remained in the " open " state , a battery can be used for six months. Be calibrated every 12 months once . Technical parameters : Power supply: 9 volt PP3 alkaline battery life of about six months. Voltage: 6.5 V <V <9 V ; 6.5 volts, shows a low voltage (LOBAT) tips. Temperature: Use : 5C~ 49CSave : -15C~ +60C Relative humidity: 0% to 90%. ( No condensation ) Accuracy : ± 5% Weight: 220 g Dimensions : 145mm × 90mm × 33mm Having to replace the battery indication
