The Tisch family was instrumental in the design of the first TSP sampler in 1954 and has been a pioneer in the air sampling industry ever since. With 55 years of experience and expertise Tisch Environmental has developed the most accurate and user friendly sampler available today.

The HI-VOL+ eliminates the need for lengthy calculations during calibration by offering an auto calibration features which requires the user to simply input the calibration factors and the system does the rest. The user must select a flow rate and the unit uses the temperature and barometric pressure to maintain that flow rate with greater than 99% accuracy. The HI-VOL+ also uses a digital timer which allows the user to set their sampling schedule only once and the system will repeat sampling events as frequently as required. The system has several data logs including and interval log, timer log, power log, and calibration log. The data interval feature logs temperature, barometric pressure, and flow rate every 5 minutes eliminating the need for a chart recorder. The timer log shows each scheduled event and records avg, min, and max temperature, epa standard flow rate, ambient flow rate, and barometric pressure.

The HI-VOL+ also utilizes an SD media card reader for data transfer and system updates without the need of a laptop being brought into the field. All data logs are stored in a .csv file format which allows the file to be viewed on most spreadsheet programs including MS excel and spreadsheet. The HI-VOL+ is a low maintenance system which eliminates the need to replace consumable goods typical with other TSP samplers
