The Model 615 Pressure Chamber Instrument has quickly become a favourite for growers making routine water measurements and scheduling irrigation. It is the product of customer input. customers requested an instrument that was fully enclosed in a sealed case with an easily removable tank. They wanted an instrument that was easily hand carried or ready for mounting on an All-Terain-Vehicle (ATV). The results of these requests is the Model 615 Pressure Chamber. PMS have recently (June 2011) updated this instrument with some changes that most users will appreciate. PMS have upgraded the Control Valve and internal piping to now allow direct connection to Nitrogen Cylinders with 207 Bar3000 PSI pressure. This stainless steel valve is more durable and has a better packing therefore giving more life. Instrument comes fitted with our most popular sealing gasket size – 14 inch Compression Gland Gasket and Insert. This gasket will seal a sample that is 14 inch in diameter down to a completely closed position. This is an excellent choice for routine water measurements in crop plants and light research in plants with little to moderate water stress The instrument has a bail-spring handle for carrying and comes complete with a shoulder strap to lighten the load in the field. It has 5 tie-down rings for mounting to ATV or other transportation. The instrument comes complete with light weight aluminum nitrogen cylinder (20 cubic foot) that is secured with 2 inch heavy duty velcro straps and can be quickly replaced with a full cylinder.
