NTU - REJECTED
Ohm A unit of electrical resistance equal to the resistance between two points on a conductor when a potential difference of one volt between them produces a current of one ampere. Ohm is also used to measure impedance and reactance for complex resistance. A measurement in ohms is the reciprocal of a measurement in siemens. ACCEPTED
PB - ACCEPTED

ppb Part per Billion REJECTED
ppm A unit of proportion equal to 10E-6. ACCEPTED
rel. bar - REJECTED
rel. hPa - REJECTED
sec A unit of time, one of the seven base units of the International System of Units (Systeme International d'Unites, SI). The second is the duration of 919 263 177 0 periods of the specified light radiation corresponding to the transition between the two hyperfine levels of the caesium 133 atom in its ground state at 0 K. According to the convention, 60 seconds constitute one minute; 3,600 seconds constitute one hour. ACCEPTED
TB - ACCEPTED

t/y - REJECTED
V A SI derived unit of electric potential and electromotive force, equal to the difference of electric potential between two points on a conducting wire carrying a constant current of one ampere when the power dissipated between the points is one watt, equivalent to the potential difference across a resistance of one ohm when one ampere of current flows through it. ACCEPTED
Vol% A unit of percentage concentration expressed as a fraction of a component by volume s in the entire volume of a resulting mixture. The unit denotes a number of milliliters of a solute per 100 milliliters of solution. The standard conditions for temperature and pressure apply. ACCEPTED
V/ (W/m2) calibration factor or sensitivity of Heat flux plate PENDING
W A SI unit of power equal to the power which in one second produces or transfers the energy of one joule. The unit is used in measurements of power emitted, transferred or received as radiation, sound waves, heat flow rate, and rate of energy transfer. ACCEPTED
° WGS84 - ACCEPTED
Wh A non-SI unit of energy equivalent to one watt of power expended during the period of time equal to one hour. ACCEPTED

µg/l A unit of mass concentration defined as the concentration of one microgram of a substance per unit volume of the mixture equal to one liter. The concept also refers to the unit of mass density (volumetric mass) defined as the density of a substance which mass equal to one microgram occupies the volume of one liter. ACCEPTED
