HovaCAL® N MF
The HovaCAL® N MF is a compact calibration gas generator for all gaseous components used in emission measurement technology and is the successor to the proven HovaCAL® digital. It consists of a supply unit with dosing devices for liquid and gases and an evaporator.
HovaCAL® N SP
The HovaCAL® N SP is a precise calibration gas generator for the generation of solvent vapours (VOCs) and gas mixtures with low moisture contents. It consists of a supply unit with dosing devices for liquid and gases and an evaporator.
HovaCAL® N VOC
The HovaCAL® N VOC is a precise calibration gas generator for gas concentrations in the ppm, ppb and ppt range for inorganic and organic solvents (VOCs).
HovaGAS N
The HovaGAS N is a highly variable gas mixer for the dynamic mixing and dilution of test gases and the successor to the proven HovaGAS digital.
HovaDEW
Dew point controlled gas humidifier
HovaDEW is an innovative method of humidifying process and calibration gases. A precision pump is used to dose water in an evaporator and mix it with a carrier gas stream.
HovaPOR
The HovaPOR series of universal evaporators generates pulsation-free vapors and gas-vapor mixtures from a wide range of fluids. Depending on the requirements, different evaporator types and evaporation methods are used.
Specialised equipment
HovaGAS XS
The HovaGAS XS is an ultra-compact gas mixer.
It provides the simplest way to flexibly and precisely mix gases for emission measurement system verification, gas chromatograph calibration, and more.
HovaCAL® N Basic
The HovaCAL® N Basic is a compact calibration gas generator designed for the precise dosing and evaporation of water (H2O) and aqueous solutions of HCl, NH3, HF, CH2O and HgCl2.
HovaCAL® CFVH 400-35-5
The HovaCAL® CFVH 400-35-5 is a compact, easy-to-use, portable calibration gas generator for generating test gases with a defined water vapour concentration of 4, 7, 12, 20 or 35 % vol. at a total flow rate of 400 l/h.
HovaCAL® N 622-SP-H2
The HovaCAL® N 622-SP-H2 generates dry and defined humidified hydrogen gas mixtures.
HovaGAS N G4-9CV
The HovaGAS N G4-9CV is a highly versatile gas mixer specifically designed for continuous emissions monitoring (CEM) systems. It precisely generates dry gas mixtures by diluting a test gas with a zero gas.
HovaCAL® N 444-SPC
The HovaCAL® N 443-SPC is a precise calibration gas generator designed for producing calibration gases from dry gases, inorganic or organic solvents (VOCs), and water vapor. It is capable of maintaining a constant humidity level in the calibration gas.
