Original product description
The DP-40 is a handheld digital meter designed to measure pressure differences between adjacent cleanrooms or between indoor and outdoor areas. It supports differential, positive, and negative pressure measurement and offers selectable units including Pa and mbar.
Its stated measurement range is ±500 Pa, with stated accuracy of ±0.25% full scale and a response time of 0.5 seconds. The instrument has a 2.6-inch industrial-grade IPS color screen with 320 × 240 resolution and Chinese and English operating menus.
Up to 16,000 groups of measurement data can be stored, with an adjustable storage period. Historical readings can be viewed on the instrument, and stored data can be exported to a computer through its USB interface. The differential-pressure zero point can also be calibrated on site.
Additional listed functions include adjustable backlight brightness, automatic shutdown after an idle period, and protection against over-voltage, over-charging, static interference, and magnetic-field interference. Power is The stated instrument dimensions are 85 × 55 × 180 mm.
Listed accessories include a USB charging cable, data-related accessory, user manual, calibration certificate, and warranty documentation.
The DP-40 is presented for production, research, environmental management, and quality-supervision work in settings such as electronics, pharmaceuticals, biotechnology, and aerospace.
Buyers evaluating it for a controlled environment should match the ±500 Pa range, accuracy, response time, operating conditions, and data-handling functions to their procedure before ordering.
Procurement questions to confirm: Ask for the exact contents of the current accessory package and clarification of the listed data accessory.
Confirm the charging and power-input requirements, data-export software or file format, calibration procedure, calibration-certificate traceability, and recommended recalibration interval. Verify whether the stated IP65 protection and listed certifications apply to the exact DP-40 configuration being purchased.
Also confirm required pressure connections or tubing, selected measurement units, customization scope, warranty coverage, and the final operating manual supplied with the unit.
