Overview Model HC-404 is a self contained, fixed wavelength infra-red analyzer designed for rapid accurate analysis of total petroleum hydrocarbons in water, soil and sludge samples. e Digital readout in %T and absorbance, or in concentration mode for direct ppm readings. * Accomodates 10, 50, or 100mm quartz cells for analysis to Ippm or lower detection levels. * Built-in scale expansion and extended linear range for high concentration, using a simple 3-step calibration. 8 Peltier cooled PbSe detector provides greater than 2500 to 1 signal to noise ratio, resulting in the very best detection levels and excellent instrument stability. ° Small foot print requires minimal lab space. Affordable Quality BUCK Scientific Hot quartz halogen source for the highest output possible. Instrument simplicity. Intuitive controls allow for immediate operation.
