Note 1: Based upon random samples until low battery warning given. These tests were undertaken on units fitted with new and fully charged Ansmann Max-e 2500 mA.Hr NiMh cells. Actual battery life may vary due to volume taken per sample, interval between samples, age of cells, and other environmental effects, such as humidity and temperature.
Note 2: One sampling head is supplied with each sampler and must be chosen at time of ordering. d50 is the mean cut-off particle diameter, Uj is the particle velocity. These figures are determined by mathematical modelling and verified b independent tests. Individual certification for heads is available at extra cost. Springs are supplied with the 220 hole head to accommodate 55 or 90mm plates. The 400 hole heads are only supplied with springs for 90mm plates. HiFlow models are only supplied with 400 x 1.0mm head.
