The securing and closing of complex and costly groundwater observation wells are part of the standard configuration of each site. It must be easy to open even in winter for check measurements samples. HT's well cap is made of a particularly tough aluminum casting alloy. A special surface treatment and plastic coating ensures optimum weather resistance.
HT's well caps for safe closing of groundwater observation wells have a suitable recess in the standard version for later installation of a measuring device such as a HT Datalogger.
We manufacture all well caps in our production site ourselves in order to ensure a consistently high quality.
