 Maintenance

 

​The following table provides a list of items that  need regular maintenance to ensure your product remains in good working condition.

 

ITEM ACTION FREQUENCY MANUAL SECTION
Inlet Clean Monthly 5.2.1 or 5.2.2
Adjust PMT with SpanDust™
(measured peak, limit: 0.0 ± 0.5)
Check/Adjust Monthly or as needed e.g., high dust load 4.1.4
Pump Performance (PWM/PID value < 80%)   Check  Monthly 5.2.4
Volume Flow
Use NIST-traceable flow transfer standard device:
5.0 LPM ± 0.15 LPM (for T640) and
11.67 LPM ± 0.5 LPM (for 640X opt) (Standard Ambient Temperature and Pressure)
Check Quarterly 5.2.5
Check for leaks Leak check Quarterly or as needed (Pump PWM or Valve PWM exceeds 85%) 5.2.8
Optical Chamber and RH/T Sensor Inspect Every six months or as needed, e.g., high dust load 5.2.6
Disposable Filter Unit (DFU) for 5-lpm flow and bypass flow (if installed) Replace Annually or when Pump PWM Value exceeds 80%. 5.2.3
Sampling Line  Inspect Annually or as needed 5.2.7

 Description

The next breakthrough in ambient particulate monitors. The Model T640 PM Mass Monitor. The T640 delivers 1-min or better time resolution with exceptional sensitivity and precision. The instrument is very low maintenance and requires no sample media for minimal cost of operation.​

 

The Teledyne API Model T640 with 640X Option is a real-time, continuous particulate matter (PM) mass monitor that uses scattered light spectrometry for measurement. The T640 measures 2.5 PM, and the 640X Option measures 2.5, 10, and coarse PM. ​​​

All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability.  All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports either locally or by remote connection.  

The Model T640 comes with NumaView software. NumaView Remote PC software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView software.
