ST-038A Monitoring and Alarming Instrument for Power Connection System
Product Introduction
ST-038A detects the contact condition between the working ground wire and the earth in real time (it can be
visible bare copper wire, dark wire and pile which are difficult to detect under the ground, etc.), and gives an
audible and visual alarm when the resistance value of the local wire exceeds the resistance value of the temple to
the earth, which effectively improves the reliability of the grounding system and is suitable for workplaces with
high requirements on the grounding resistance value.
The grounding system monitoring and alarming instrument can automatically alarm and monitor and alarm the
grounding system condition in real time; The monitoring resistance value of grounding system is adjustable
(0-500Ω); According to the requirements of the grounding resistance value of the work line, set the grounding
monitoring ** resistance value, and when it exceeds the set resistance value, an audible and visual alarm will be
given; Sound and light alarm immediately when grounding system breaks.
Product Function
1. Automatic alarm, real-time monitoring and alarm of grounding system condition.
2. According to the requirements of working grounding resistance value, set the monitoring resistance value to
the ground. When the set resistance value is exceeded, SL-038A will give an audible and visual alarm.
3. Acousto-optic alarm is given when the grounding system is broken, which effectively improves the reliability
of the grounding system, LCD display and lockable setter. It is suitable for workplaces with high requirements
on grounding resistance.
4. The monitoring resistance value of the grounding system can be adjusted (0-500Ω), and when the loop
resistance of the local line is higher than the set value, an audible and visual alarm will be given immediately.
It can also be used as anti-theft system in factories and garages.
Product Features
1. LWBATTERY indicator flashes when the battery voltage is lower than 7.5V.
2. Digital display of temperature and humidity
3. Multi-functional tester for measuring environmental temperature, humidity and surface resistance
