Description

Product introduction

DP-30 was developed and designed by Suzhou HjClean Technology Co., Ltd. to fill the domestic gap and has applied for national invention patents and utility model patents; this equipment is mainly used for on-site HEPA filter system integrity testing. The scanning probe can provide all the functions of the host. Through performance verification, data and facts have proven its international advanced level in terms of sensitivity, accuracy and other technical indicators.

 

Application environment

Product parameter

size 260mm×370 mm×160mm
weight 10kg (host) + 0.5kg (probe) =10.5kg
Instrument shell

The instrument casing is sturdy, made of die cast aluminum. When internal components are repaired and recalibrated on time, they are easy to assemble. The shell has a handle for easy handling;

power supply 220V 50/60HZ
Automatic range Automatic from 0.0001% to 100.0%
alarm When the adjustable set point is exceeded, the built-in audio alarm will sound. The video alarm on the control panel and scanning probe will flash. The sound alarm function can be adjusted or cancelled;
Aerosol collagen solution can be set PAO、DEHS、Ondina
dynamic range Up to 600 ug / L
sensitivity 1% of the readings in the range greater than or equal to 0.01 to 100%
repetitiveness 0.5% of the reads in the range greater than or equal to 0.01 to 100%
output RS232 port connection or external printer (optional) illuminant
illuminant Long, stable, solid state scattering chamber light source. The luminometer operates at low power, produce less heat and low deviation values. The estimated life span is 50,000 to 100,000 hours;
Random attachments Two sampling tubes; Operating manual, certificate of conformity, warranty card, power cord
optional Portable case, printer
report Continuous mode, storage mode, printing mode
scanning probe Sturdy and comfortable handle design, equipped with a 2.5m connection assembly, 2.8-inch LCD display, in case of exceeding standard alarm

Application principle
When the air passes through the device, the suspended particles in the sample scatter through the light chamber, the scattered light will reach the light multiplier tube through the dark cone, the light signal is converted into an electrical signal, the signal is amplified and converted into a digital signal, and then the microprocessor analyzes the light intensity through the light scattered signal. This signal is then compared with the provided reference signal and then output.

 

Product advantages


(1) More friendly interface ———— host adopts 3.5-inch LCD display, fully absorbed the advantages of international famous brand product operation interface, and add real-time concentration data display, using theme driven interface, easy to use aerosol measurement, the vacuum pump sampling speed on the LCD, easy to observe; for the selected alarm type and alarm point, in the dish. There are instructions on the sheet; the top displays the connection status, alarm type and report type.

(2) Portable scanning probe
The scanning probe is connected through a circuit as an extension of a host, given by
With the control state of the host, the selection icon is displayed on the 2.8-inch LCD. This makes the inspectors greatly improve the work efficiency, can immediately find the leakage and make a prompt.
(3) Easier to trace test results ———— DP-30 has three independent reporting functions, printing mode, storage mode, printing and storage mode (including filter location and other content can be output through the thermal printer for customers to save).
(4) Performance assurance ———— DP-30 adopts the original imported sampling pump and Japanese imported light source, the core component sensor adopts the domestic top high precision processing technology (the same standard as the technical requirements in the domestic aviation field), the instrument has been independently tested and verified, meet the requirements of electronic and safety standards.
(5) More perfect and fast after-sales service ———— DP-30, as a domestic independently developed luminometer, can provide cheaper after-sales service, host software lifetime free upgrade, prototype support.
