Even more surprising for Muller was the final measurement against the company's reference laboratory pH standard
using pH 1.08 hydrochloric acid; here again the 8201 proved itself superior.

The absorption at 630 nm of a series of pH buffers mixed with dye solution was used to construct a pH standard
The electronic pH meter (Elico, LI -127) was calibrated using 7 pH and 4 pH standard
With good insulation, minimized thermal bridges, airtightness, optimized glazing, and heat recovery ventilation the annual specific net energy demand according to the PH standard
for net space heating and ventilation is 15 kWh/([m.sup.2] x a), while the total primary energy for space heating, domestic hot water, and household appliances may not exceed 120 kWh/([m.sup.2] x a).
He also reset his own PH standard
of 50.46 seconds set in 2013 by clocking 50 seconds flat during the heats of the Incheon Asiad.
Our results suggest that the water is suitable for domestic, fishery, and recreational purposes with reference to pH standards
