Easy operation

The operation of the DS404 docking station couldn't be any easier. Simply put the G450 or the G460 in the dock and the system will take over from there. The DS404 automatically performs a full functional test including fresh air calibration, bump test, extensive sensor tests, alarm tests and optionally performs an automatic AutoCal® calibration.

Extensive diagnostics

The DS404 is designed to go beyond the traditional basic docking station tests and includes sensor diagnostics tests such as T50 and T90. After all, what good is a sensor that can respond to gas when it takes too long to get there? With the DS404 you can have confidence with this added level of safety.

Automatic charging

After all tests have been completed the DS404 will automatically start the charging process of the detector or you may remove and begin using it. In case the detectors battery condition is insufficient to complete a test the DS404 will charge the instrument before performing the test.

Record Keeping

A good instrument gas detection maintenance program is not complete without equally good records keeping. Whether you choose to download or maintain the records on a PC or network or your preference is to leave it to the docking station, the DS404 is the right choice.

The DS404 can retain as many as 2 million complete diagnostics in memory with maximum memory installed. That is over 50 years of data even if testing 100 detectors every single day!

Reduced cost of ownership

The DS404 is designed to reduce the cost of ownership every step of the way. The built in pump has variable flow control to reduce the amount of gas consumed during the test. The DS404 is even smart enough take advantage of the gas remaining in the tubing after the previous test was completed.

PC communication

The DS404 comes complete with USB interface cable and download software. The SD card may also be downloaded using a standard SD card reader.

quickly print official calibration or bump test certificates. Simply download the records from the DS404 and start the "Certificate Generator" it takes only seconds!
