Multipoint Sampler e Dosador

The INNOVA 1403 is a reliable, easy-to-use and remote-controlled Multipoint Sampler and Doser that combined with the Photoacoustic Gas Monitor INNOVA 1512 and a controlling computer with Basic Ventilation Software INNOVA 7650 offers wide-ranging monitoring capabilities.

Multipoint Sampler e Dosador INNOVA 1403

Key Features

  • Full remote-control from a PC with Basic Ventilation Software 7650
  • Automatic calculation of the amount of tracer-gas delivered, to the dosing location
  • Factory calibrated dosing system
  • Self-test function
  • Pneumatic system constructed of AISI-316 Stainless Steel and PTFE tubing to minimize gas adsorption


An increasing number of legislative measures are aimed at improving air quality in workplace environments. These improvements require gas monitoring equipment with the flexibility to provide sensitive and accurate monitoring in a variety of environments.

The Multipoint Sampler and Doser INNOVA 1403 from LumaSense Technologies is designed to be remote-controlled from a PC using a USB interface with an Photoacoustic Gas Monitor INNOVA 1512 to provide a flexible, sensitive and accurate monitoring system. The 1403 greatly increases the area monitoring capabilities of the 1512 by drawing air samples through tubing from up to six sampling points, up to 50 m away, and delivering them to the 1512.

Comprehensive air exchange analyses and ventilation efficiency checks are easily performed using the 1403’s dosing facilities. Tracer gas is delivered through tubing to “label” the air. The amount of tracer gas delivered is automatically calculated by the 1403. The labeled air is then sampled by the 1403 and delivered to the 1512 for analysis.

The 1403 factory calibration and self-checking routines allow for easy verification of the unit’s operation and ensure reliable functioning.

Application areas

  • Air sampling in 6 locations, and delivery of the sample to Photoacoustic Gas Monitor INNOVA 1512
  • Delivery of tracer-gas to locations for air-exchange analyses with Photoacoustic Gas Monitor INNOVA 1512


Technical Data

The 1403 must not be placed in areas with flammable gases/vapors in explosive concentrations, or be used for tasks in which explosive concentrations of these gases/vapors are monitored. Also note that certain aggressive gases could damage the internal airways of the 1403. Contact your LumaSense Technologies’ representative for more information.
Height: 155 mm (6.1 inches)
Width: 445 mm (17.5 inches)
Depth: 260 mm (10.2 inches)
Weight: 10 kg (22 lbs)
Sampling System
The following pressure and volume-flow data assumes the use of tubing of length 50 m and internal diameter 3 mm.

Sample transport speed: 2 m/s
Three-way valve routes samples either to waste-air outlet or to the connected 1512.
Minimum pressure, blocked airways: 40kPa
Dosing System
The following pressure and volume flow data assume the use of Sulphur Hexafluoride (SF6) or Freon 134a (R134a) as tracer-gas, and Nylon tubing of a length 50 m and internal diameter of 3 mm.
Pump Performance: Minimum working pump-pressure: 10kPa Volume flow rate of supplementary air per dosing channel: 4 ml/s
Tracer-gas Supply: From pressurized cylinder
Supply pressure: 300 kPa +/- 10 % absolute
Mass Flow Controller
The delivery of tracer-gas is controlled by a Mass Flow Controller. The volume flowrate is variable and is dependent on the selected tracer-gas.
