Hilase instruments

A typical Hilase instrument contains one or two telecommunication type diode laser (with the exception of the MuWaPas instrument, which is based on a Nd:YAG laser and on its wavelength converted harmonics), a high sensitivity detection cell or cells and a fully programmable DSP based electronics for complete system control, concentration calculation, data storage and transfer by using various communication possibilities such as 4-20 mA, RS232, RS485/422. Various communication protocols can be used such as Modbus RTU etc.
