Spectrum SP Series Gas Detectors

Gas detectors are designed for monitoring the environment by one of two methods, diffusion or sample draw. In the case of diffusion, natural forces are relied upon to cause the ambient air to interact with the gas sensor. As an alternative, the air sample can be drawn to the sensor using either a hand-operated, squeeze-bulb aspirator or a motorized sample pump. Obviously, the motorized pump is much more convenient and easier to use, and it can provide a continuous air sample to the sensor at a constant flow rate.

Sample draw reduces gas response time compared to natural diffusion, and it facilitates testing of valves, pipe connections, etc. for leaks, and enables the monitoring of remote areas or enclosed vessels where non-ambient conditions may exist, such as, temperature extremes.

A properly designed sample draw system can improve the monitoring performance for most gases, particularly acid gases like CIg and HCI. It also reduces the response times for gases to be detected at sub-ppm con-centrations, such as, AsH3. And, most important, sample draw is required for the detection of some gases, most notably, HF and O3. It is for these reasons that the SPECTRUM SP Series was developed.

Formaldemeter htV
The Formaldemeter htV offers a simple way to monitor levels of airborne formaldehyde in the environment. The instrument is easy to use with a simple four button keypad and features an easy-to-read four digit display. It employs a well-proven electrochemical formaldehyde sensor that will provide an immediate indication of formaldehyde levels. Unlike other formaldehyde monitoring devices, such as color stain tubes and badges, the Formaldemeter htV is capable of measuring many samples consecutively without the need for inconvenient ancillary equipment. Real-time results also mean that potential overexposures can be identified as they occur, without the delay and expense associated with laboratory analysis.
Also available: the Glutaraldemeter 3 for glutaraldehyde monitoring
  • Easy to use - minimal training required
  • Rapid response time
  • Small, hand-held instrument
  • Lightweight
  • Built-in sampling pump
  • Standard 9V alkaline battery operation
  • Temperature and humidity can also be displayed
  • Reliable electrochemical sensor
  • Simple in-field calibration
  • Optional base unit for continuous monitoring
Applications:
Formaldehyde is a common contaminant found in new construction, residential housing and commercial buildings following renovation. It is used in many products, industries and other types of activities, including:

Textile treatment
Medical labs
Laminated boards
Pharmaceuticals
Synthetic resins
Horticulture
Paints
Mortuaries
Paper products
Biological
Dye stuffs
Particle boards
Commercial buildings
Cosmetics
Residential construction
Hospitals

Operation Details for Formaldemeter
Sampling:
  • Press the ON-OFF button
  • The display will show "---" followed by "0.00" (sensor ready)
  • Press the SAMPLE button
  • The display will show "run", followed by the sound of the pump sampling the air
  • The display indicates the measured concentration in approx. 10 seconds
  • Switch the instrument OFF (Instrument will automatically shut off after 5 minutes)

High levels, i.e., over 1 ppm, can take at least 5 minutes to "clear" from the sensor. If formaldehyde is detected, wait 3 - 5 minutes before turning instrument ON for next sample. To take another sample, repeat above steps.

Retrieval of stored data - instrument automatically stores the last ten readings

  • With the SAMPLE button depressed, press the ON-OFF button and then release
  • Instrument will display "HEAT" followed by the temperature in "C", alternating with humidity in % rH
  • With the instrument in this mode, press both CAL buttons simultaneously until the display shows "dAtA"
  • The display will now show "run0" followed by the result of the last sample
  • Scroll to the last ten results using the CAL buttons

Accessories and Replacement Parts:

Phenol Filters (supplied with instrument kit)
These filters can be used, when necessary, for the removal of phenol and resorcinol

Calibration Standard (supplied with instrument kit)
The calibration standard is a tube which produces a known concentration of formaldehyde vapor for testing and, if necessary, adjusting the accuracy of the monitor. The standard has a 100 sample capacity or a useful life of six months, whichever occurs sooner.

Options:

AMS-2 Base Unit
The base unit automates operation of the Formaldemeter htV for semi-continuous sampling. Monitoring of all three parameters (formaldehyde, temperature and humidity) is possible with the AMS-2, giving real time data and alarm (TWA/STEL) levels. A built-in printer provides a record of the results. All data is stored and can be downloaded to a PC via RS-232 and available download software.
AMS-2/htV Download Software
Data logged into the AMS-2 can be viewed on the LCD and outputted to the integral printer. If required, the data can be downloaded to most PC based spreadsheets using the AMS-2/htV download software
