Rainfall on-site calibrator model: JF-1


1. Product Overview
Our company designs and manufactures a tool that can monitor and calibrate rain gauges on site. It has two modes: counter mode and calibration mode. In timer mode, it can count up to 9999999, and in calibration mode, it can calculate the number of rainfall buckets, rainfall duration, rainfall intensity, and rainfall error. This instrument uses a two-stage steady flow bucket to ensure stable rainfall intensity and can provide simulated rainfall intensities of 4mm/min and 2mm/min. This instrument is powered by lithium batteries and can be used continuously for more than 8 hours on a single charge. It also uses an OLED LCD display screen, which can clearly identify the content of the LCD display even in strong outdoor sunlight. The instrument has a small size and is easy to carry. It is suitable for on-site calibration and testing of tipping bucket rain sensors, such as automatic weather stations and hydrological stations with a diameter of 200mm, daily maintenance, regular inspections, and reactivation.
2 Main technical parameters
2.1 Tongde Entrepreneurship Rain Intensity Control Indicators:
Heavy rain intensity (4mm/min) drip time: After injecting 10mm clean water into the two-stage steady flow hopper, the complete drip time is 2'30 "± 10".
Medium rain intensity (2mm/min) drip time: After injecting 10mm clean water into the two-stage steady flow hopper, the complete drip time is 5 ′ 00 Ω± 1 ′.
