How to use it

  • Test and record disinfectant residual, pH and temperature several times a day as set out in HSG282 and your operating procedure.
  • Record approximate bather load and any dilution, dump or filter backwash carried out to maintain water quality.
  • Act on and log any reading outside your control range - dose, dilute or close the spa as needed.
  • Treat the recommended residual/pH ranges and microbiological sampling intervals as per HSG282 and your own plan; the values shown are illustrative readings, not targets.

Background: Safe operation of spa pools and hot tubs under HSG282
